I think you're trying to spin the truth here. We have no proof whether Future Rogue can outclass Laxus in speed but do we have any reason not to believe so? Somebody like Mystogan can dodge from Laxus attacks and such so Future Rogue can do the same whether it is speed or intangibility...
You're not scaling the attacks right and you fail to understand the idea of concentration. When there is less of something, it tends to have larger concentration than large r samples. Same thing here. The size of the magic attack can be less but beams can be concentrated with high magical energy which is seen in the Etherion Blast. How is Tower of Heaven DF Natsu stronger than GMG LFD Natsu? Natsu unlocked his Second Origin before GMG even started. Therefore, he should well be stronger than he was years ago.
Mystogan could keep up with pre-timeskip Laxus before he used Lightning Body. LB Laxus was faster than Hades, who handled casually Erza, Wendy, Natsu, Lucy and Gray. And this was pre-timeskip. Or is Future Rogue even faster than Hades who has far better combat speed than Base Natsu?
Naw, I don't have to judge the concentration of the attacks simply because the best we can get out of Future Rogue's attacks is being tanked by LFD Natsu while Jellal can clearly output higher energy levels in his attacks. Simply put, Future Rogue's attacks can't take down Jellal (since Jellal's durability is higher than LFD Natsu's) and those attacks would affect a small area since they're more concentrated. And Jellal has shown attacks that have enough potency to handle Future Rogue regardless of the concentration.
We're comparing different modes. If GMG Natsu had an Etherion-induced Dragon Force, I could say he was stronger than ToH DF Natsu. However, this is LFD Natsu and ToH DF Natsu has better feats than that version of Natsu.
Jura was able to hit Jellal during mid-flight when he used Meteor/Grand Chariot... We don't know if Jura was toying with Jellal and I don't think he did either but know that Jura was standing in one spot with Jellal on the offense. So, although it looked like Jura was overwhelmed, he might not have been.
Jura was also standing in one spot against Laxus, and it was clear that he wasn't toying with him. That was Jura's spell, not Jura (who couldn't react when Jellal passed by him), if you know what I mean (spell speed =/= user's combat speed). Also, Jellal was casting a spell, so that would be considered as off-guard.
No, it wasn't explained well. Just look at his condition after the fight. You're comparing the events incorrectly. Natsu was pretty much on the verge of death. Whereas, Future Rogue was barely scratched until the end. Natsu knew he couldn't kill Future Rogue so he had no other choice but to destroy the Eclipse Gate which would make him disappear from present time. Jellal, on the other hand, was utterly defeated and had to be resurrected by Oración Seis.
What matters is that LFD Natsu was fighting on par with Future Rogue. And I've proved why ToH DF Natsu is stronger than LFD Natsu. Jellal tanked two of DF Natsu's attacks (tanking or not, it accounts for durability) after fighting Erza and Base Natsu. Either way, Future Rogue won't have the durability to tank spells like Sema.
Fairy Tail is not based on physics or someone like Jura should have owned Oración Seis due to the nature of his magic but remember he lost to them. Someone like Gray would be one-shotted but it didn't happen. Laxus beat Jura. Can Lightning really defeat Earth in real life? No. I can list many other instances but my post would be too long. Mt. Fuji didn't take longer to charge than Sema and because we don't know how much defense it really provides, it would be pointless to discuss it.
We can say it's based on physics until it's shown othewise.
Jura stomped Brain. What does "the nature of his magic" even mean?
Why would Gray be one-shotted? He has clear durability feats, so I don't get your point.
The fight was Jura vs Laxus, not Earth vs Lightning. It was mainly a CQC battle, there was no elements battle.
I don't care, what matters is that Sema was portrayed to have overwhelmed Jura's durability if no counter spell was casted.
-DF Natsu pretty much owned Jellal in their altercation. Jellal was even knocked out temporarily, and he barely managed to endure a few attacks from DF Natsu. He was getting ragdolled in an even more brutal fashion than Jose did to Erza.
Jellal took two attacks and kept fighting right afterwards. That accounts for durability and that's what matters.
-Where's the inpanel proof of Laxus being slower than Jellal? Speed-wise, Laxus's short term blitz travel faster than Jellal's meteor does on the duration of velocity.
What? Jellal passed by Jura before he could react whereas Jura kept up with Laxus. Meaning Jellal > Laxus in speed.
-Look at the characterizations. Jura had to take his coat off and had a serious expression against the time he fought with Laxus
Jura's fight with Jellal had him resorted to not taking off his coat and smiling the whole time.
So Jura has slower reaction speed when he's not bloodlusted? No, nothing actually indicates so. Jura showed he was serious when Jellal started going around him and casting Grand Chariot.
That pretty much tells you Jura was serious in one occasion, and non-serious the other one.
Jellal on the other hand had every reason to be serious in order to clear his debt to FT, and he even resorted to using his strongest spell in case of desperation.
No, there was no clear indication that one version of Jura was much stronger or faster than the other. In fact, Jura's best feats came from the battle against Jellal.
Did some say Laxus is slower than Jellal after watching their battle against Jura? I doubt that. I hope this can be a consideration. Laxus clearly used his lightning body and targetted Jura directly, that's why Laxus got hit by Jura. Meanwhile, Jellal blitzed him circularly and targetted his side or back.
Don't you remember Laxus skillfully dodged Jura's boulders that appeared from ground without getting hit? That's right after Laxus casted Heavenward Halberd and Jura used Callus. Meanwhile, Jellal got hit by one of Jura's rocks when he drew Grand Chariot patterns.
No statements are needed when we have in-panel proof.
But Jura had to
react to Laxus to hit him, something he didn't do against Jellal.
Jellal was caught off-guard since he was drawing Grand Chariot patterns whereas Laxus was fighting head-on against Jura.
