There's absolutely no way Zoro has regen breaking CoC and Luffy doesn't. Surely we're not gonna have another rooftop situation where after all the clowning it turns out Zoro was on par with or greater than Luffy the whole time ☠️
Whilst that'd be hilarious from an agenda perspective, in reality nothing suggests an attack with regen breaking ACoC is necessarily stronger than an attack without it, same way an attack without haki at all can be stronger than an attack with haki - all that matters is overall AP.
If Zoro does have it, however, I don't wanna hear anything about him still being a level below the old legends. Also this confirms all the top fighters of the new gen will develop ACoC, so Sabo, Kid, Coby, Sanji and potentially even Law fans can rejoice. Everybody winning (except Luffy fans lowkey)
