I know I'm a God Serena-tard but that doesn't mean that I don't judge all characters equally. When I say God Serena wouldn't be defeated by Laxus is because I operate under the assumption that God Serena is superior to Ajeel or Wahl.
Is it a baseless assumption? It is not. All spriggan were said to be on the same level as all S-class mages were said to be on the same level. Then it turns out Laxus and Mystgun were much more powerful than Erza and Mira, and that Glidartz was above everyone.
So we shouldn't just stick to the same old portrayal. It is rather clear not all the spriggans are as powerful. They may have similar amounts of MP, but MP is not everything. Neinhart has enough MP to summon 3 Spriggan-level characters and his durability is shitty, so one thing makes up for the other (extreme MP (maybe superior to other spriggan's) + shitty durability = spriggan level character).
I believe Laxus wouldn't be capable of beating Serena as much as I think he wouldn't be capable of beating Dimaria. And if according to you, all spriggans bar August/Irene are on the same level, then you must agree that Laxus could solo all of them bar August/Irene, am I right?
They are equal and everyone bar Irene and August has been put on the same level. August much later wasn't stated to be wayy stronger, Makarov literally treats every Spirggan he knew on the same level bar August. Irene was hyped later on because she wasn't one of the six Spirggans Makarov knew about, Lacarde himself isn't much stronger than his peers is was specifically pointed out that the nature of his MP was different not that he has way more than his peers, while his move set could be the reason he beats ACno not because he's way stronger. All Spirggans bar August and Irene are not the same level, you just need to get off Serena's nuts.
You may stick to the same old portrayal if you want and I'm gonna respect your opinion (operating under the assumption that all spriggans bar August/Irene are equals). Now I think I've got my reasons to think otherwise and you cannot deny it. The performance of different spriggans has proved that they rank differently. Their hax and powers also proves they could beat enemies that others simply couldn't.
If God Serena happens to posess the lightning element, it'll be the same case scenario as against Wahl: God Serena will not be affected by him. We don't know God Serena's CQC abilities but we do know he tanked a Wolfheim punch and he was harmless. If you ask me Wolfheim's punch should be > Laxus magicless punch.
Beating the 3 GoI+Jura means nothing when we don't know how strong they were in the first place. His performance against the main cast? They literally stood in both of his move completely unaffected, his performance wasn't impressive.
By that same token, if we don't know how strong they were to begin with, how can you claim 'it means nothing' to have fodderized them? You could at least say "we don't know if defeating the 3GoI+Jura is nothing or actually means something".
Why? Glidartz > Laxus, Laxus high diffed Wahl but he was at a disadvantage, normally he'd easy-mid diff him, so Glidartz easy diffs him. Around the same for Ajeel.
