Yeah it makes sense in a way. We don't know for sure what would happen but it certainly seems plausible that BnHA could get insanely better after a break, but ehobknoes, since it probably won't happen. Hiatus=death IMO.

The following is a response on Boku no Hero merits and room for improvement (and slightly, Black Clover).
I wrote way too much. 
If you could skim it and give me your opinions, I'd be grateful. 
Gonna add semi-random emoticons everywhere so you get less bored.
Hey there, interesting reply. I get annoyed when the debates on series go on too long, so if I can control myself, I think I won't reply after your next response. I'll still read it of course, but it looks like we differ only on opinion and individual enjoyment, which isn't something that we can really reconcile. Here, I'll justify my opinion slightly before I drop the subject, since we don't need the whole "digital sales"-length argument again, IMO.
The following is going to be a bit sassy but tbh I quite like Boku no Hero. Top 10 or Top 5 shonen to be sure. I'm only just saying this so you guys know, that i'm not just trying to bash Boku no Hero.
- Its progression of character skillsets is paced extremely poorly, with the majority of characters never levelling up except during "class wide training arcs" which showcase them for ten seconds and then are never seen again. Even deku's powerups are getting boring. We've already seen 100% technically. So what could possibly be next? As opposed to nen and devil fruit which are more flexible yet make internal sense, the powers in boku no hero are getting extremely restrictive IMO which leads to it being tough to make this better as well.
===> Basically too many characters, restrictive skills, is what it is. Also, at this point characters are just pulling moves out of their ass, or training in the background and then pulling moves out of their ass, or doing moves that in-universe make sense but that we've never seen anything about the character before so there's no way it can't make sense. Especially in the recent team fight chapters. So it's literally the same in my eyes as black clover at this point in terms of how ass-pull the attacks are, which is toning down the realism for me. Especially Manga's attack, like how do you expect to keep the realism in the manga without building that up for a while before introducing a literally sound effect attack. Even Koichi in Jojo built up his sound powers up over a hundred chapters, and even then there was a feeling of shock and discovery of the characters to facilitate that skill growth. 
===> TLDR: Skillset development could be better. Too many characters, not much freedom once your Quirk is determined, and killing the realism.
- Up til now, I think the team fights have not been meeting their potential. In the past, all team fights have been is character A attacks and then character B attacks. There are way more fights that essentially end up being mano a mano despite technically having more people involved. The ones I can think of is Stain, in which the "team" component is both Deku and Iida punching/kicking the guy at the same time, and also when Todoroki wasn't paralyzed he used his powers. I wouldn't call that great team play. When they rescued Bakugou that was making an ice ramp and running on it. Not a creative use of all of their abilities IMO. In the playing with toddlers arc Todoroki did what...? Oh, he made another ice structure. And then the wind guy did what? Oh, he made a hurricane... which is literally all he's done since he was introduced, to break the ice structure. And luckily it looked as beautiful as a lights show.
===> It's only in the recent team fights that we see a bit of creative teamwork with fun combos. Hoping this carries on to the future. To me, it feels like this arc is Horikoshi playing with the characters and seeing which combos work best, and thus didn't need to be in the manga. He's basically infodumping the character's attacks and reminding us that the 40 kids exist, via a team battle that plot-wise didn't ever need to happen. I don't have much hope that these team battle tactics will be carried through into the future, even though they have barely just begun developing. (Besides the obvious Shinso's useful ability.) 
===> TLDR: Teamwork is either nonexistent or basic. Hopefully more fights like the ones in the recent arc will happen from now on.
- I honestly find the battle scenes to be hard to understand. I actually agree that the gomu gomu enemy had one of the best battles for fight choreography, but choreography is my next point. Here, I want to point out that it's really convoluted and hard to understand. This image https://s2.mangadex.org/data/4f1aa1421cbd51a6516acb0d9cc4dd5f/A8.png (not picking and choosing too unfairly here) represents the confusion. So panel one, gomu gomu jumps on Deku? But next panel we see Deku has taken a blow to the gut? And next panel he's moving in straight lines all around the panel, which I'd say is logically easy to understand, but not a great way to do it.
===> I think Bellamy's hops around the screen, Luffy's snake mode arm hopping around the screen, and even Speed of Sound Sonic hopping around the screen to an extent is done better than this hopping around the screen in terms of understanding his actual motion. In that panel it just feels like the motion of a bowling ball being launched around, instead of a human having to adjust his landings, actually creating the rubber landing spots, etc. etc. Not all of this is well conveyed to the fullest of its potential. 
===> TLDR: Human movement is not well portrayed. He is extremely good at drawing poses, but the transition/movement between poses (I'm guessing) is what is throwing some readers off.
- In terms of choreography, I would say, check Gintama for amazing hand-to-hand/sword-to-sword fight choreography, which is essentially what 90% of Boku no Hero's battles boil down to anyway, punching and kicking or occasionally launching projectiles. As you can see in the gomu gomu battle the choreography is basically the guy bouncing around in straight lines. Basically Bellamy, and that guy only deserved two pages to take him down. It's simply not interesting for the battle. Also as I've said, the All for One fight was just more and more punches. Might as well just one-panel ORA ORA ORA him (obviously not, for thematic and emotional purposes, it's just a joke guys.)
===> The Endeavor fight was shooting fire, then getting ... actually let me check again, it was so bland I already forgot. Okay so the new model enemy was swinging its limbs. Endeavor blasted the guy with fire. Then he launched himself with fire and punched him. Then he did that again, but extra hard and called it prominence burn. And for teamwork Hawk threw some feathers at the guy. And throughout the whole thing there was linear movement of them chasing each other. Of course, it was presented beautifully, and especially launching Endeavor through the building was jaw-dropping. But the choreography boils down to "punch him away" except it's really hard punches that push you in a straight line through a building now. 
===> I think it's because I've been pampered by Gintama's choreography that I can look back on this a bit critically now. Check this chapter out, where he starts fighting Oboro in the courtesan of a nation arc. (not gigantic spoilers, in this chapter, but still some) https://mangadex.org/chapter/77940. And around the parts at 1:45 and 2:55 in this amv to see how easily that translates to fluid motion in the anime. Boku no Hero's first and second seasons went crazy with the amount of translating motion but in the 3rd season it's been a little rough especially due to the movie, and it's been a lot more linear in nature, since that's all the original work gave them in terms of motion anyway. 
===> TLDR: Too much linear motion, attacks are just harder and harder punches/hits. Powers/settings could be used better.
And all of that is not even considering the untapped potential of the larger world, even within Japan; character development/backstories; pacing and having more cohesive themes throughout; having better flow and transitioning between stories, etc, which I think are bigger issues than all of the above.
Honestly to be the devil's advocate maybe if Horikoshi took a break, and reviewed a bit of what other mangaka are up to, not that he's any less than them, but just as a quick refresher, I think he could come back with a lot more ideas. Because slowly, it does feel like he's, if not writing himself into a corner, making it harder and harder for him to write an interesting story, since he is so burdened by the rigid laws of the society he created, the rigid boundaries of the super powers he created, and the unchanging, constant school setting he locked himself into. The initial setup of a manga is everything, even 300 chapters down the line, and Boku no Hero made a few choices in the beginning that could have been chosen better IMO.
And if anything reviewing other manga could get him to see if he's inadvertently copying anyone else's ideas. I'm sure he isn't doing it intentionally but he basically took the bridge-building arc in Naruto, that bratty kid's backstory where his parents died, and brought it to boku no hero. There's a saying in the writing profession that authors should read everything there is to read, if not to learn, then to realize what's already been done. Even now, the whole "past generations of the one for all" just reminds me of the Vongola of Reborn. And I'm willing to bet a couple bucks that they have close to zero relevance going forwards, or maybe they'll finally come up again when we forget who they are.
TLDR: Skillset development, teamwork, direction/choreography of battles, among other things could be better.
And if I'm just to shill Black Clover for a second, it definitely doesn't lack in those four things. It may lack realism, but Boku no Hero's realism has been dropping consistently for me since around the Stain arc. Black Clover's character design, emotional impact, power of its panels, and originality of characters and story is definitely not a match for Boku no Hero.
However one thing that has changed is, it is developing the world better than Boku no Hero is now, since in Black Clover, the original setting is that they get to go out and adventure randomly, which is nice and unrestrictive, but on Boku no Hero, they literally need an excuse to leave the school since they're trapped in there for security's sake. Horikoshi literally has to write himself out of plot holes just to get them to go out of the school, and the school setting has been getting stale for me. He says he wants to continue it for 30 to 40 volumes but at this rate if the whole time they're in school... anyway that's a digression.
Also, mostly simply, "quality" and all aside, Black Clover has just gotten to be more fun to me than Boku no Hero. Which is 100% taste-based, so the majority of you that enjoy Boku no Hero more, are 100% in the right. For me, it's just that Boku no Hero doesn't seem to have a clear direction throughout, and even within smaller arcs. It doesn't paint you a picture of coming events IMO. Like could you expect this progression of events? Raid on training camp -> Fight against the endgame boss -> Another tournament arc -> Attacking a Yakuza's base -> School festival -> Endeavor and Hawks vs ??? -> another tournament arc (basically) -> I don't think I'm being unfair with this, the tone and theme shifts around too much to be realistic, but takes itself too seriously for us to feel that this kind of thing can happen naturally. Right now the simplicity of Black Clover is really to its favor. Each chapter we know that they're going to fight the elves. And then after this arc there is a vs. Diamond Kingdom arc. Etc.
It's more fun, the attacks are more imaginative since there's less restrictions, and you get a team-feel out of it kind of like Haikyuu. Boku no Hero right now, especially recently, feels like the same old characters, in their subdued, realistic manners, but they're using these insane attacks on the most low-scale fights that haven't built up enough for us to care at this point.
Imagine Boku no Hero but instead we already know that next, the MC is fighting Big Mom, and then Kaidou, and then Blackbeard, and all the challenges he has to overcome, etc. I think there's a direction that's lacking.
Final TLDR: Boku no Hero set us up for a gritty, realistic, fast-paced, character-centric story but has been tied down by slow large-scale plot development, low character development, an excess of restrictive rules, a restrictive setting, and hopping around thematically and not having a clear direction. I believe it can improve in terms of presentation as well, as discussed in the four points above.
LOL. Sorry for writing so much. Also I just woke up, so I'm sorry for cancerous grammar.
And I'm sorry if I sounded way too elitist... I just got here and yet I'm writing books about how "me so smork" and "BCchads > MHAchads". Sorry haha.
Time to study for exams. Thanks for having me.
