Uh oh, y’all had better get ready. If Yamato has AdCoC, then get ready to enter the point in the story where literally everyone has AdCoC, just as I predicted lol.
As if Oda hadn’t been fucking up enough lately, the only thing worse than actually introducing AdCoC into the story, is giving it to every relevant fighter in the New World, and that’s the route we’re heading towards lol.
I feel you on that, but at the same time it would be even weirder if a small percentage of the actual top tiers don't have it, just because "fuck it- balancing abilities", even if they might have CoC and already are advCoA users.
I mean it's not really difficult to make use of afterall.. In contrary to FS or internal destruction it does not need to be awakened via a haki bloom or something. Characters only really need to know that it's possible to make it flow aswell and they are good to go.
Imagine a guy like Kizaru getting confirmed as a CoC user, that already can make his CoA haki flow, but then does not have it, because "light fruit is enough on itself" reasons or something.. Would be hella weird and nonsensical tbh.
And honestly if Yamato also can use it, everyone probably would want the real heavy hitters to be able to use it aswell.
That's why I'm positive that Luffy's CoC spec is not just for show and there is still something coming for the potential supreme CoC users, namely guys like Roger, Shanks and EoS Luffy.
And because it's probably not stackable with all kinds of DF abilities I think for guys like the admirals it might not even be their most powerful asset, all the while super enhanced brawlers like Luffy & Kaido or top tier swordsmen benefit much more from it, ultimately leading to still very interesting fights.
