We only have 2 confirmed IDCoA users and Hygoro called it an extremely rare ability that he can't replicate
idcoa is not hinted to be required for Kamusari. So i don't know why you're bringing that up.
AdCoC is also a very rare ability that is used by the strongest according to Kaido.
Literally yamatoe, zoro etc have it.
And I don't understand why we're acting like Ray doesn't have portrayal of a solid top tiers
Roger is not just a solid top tier tho... He's one of the god tiers of this verse.
And shanks is supposed to be the middle gen Roger.
So if Ray can replicate this technique it will still be very rare even among top tiers.
That's not what oda said. He said not anyone in the Roger Pirates can replicate. It should be obvious to anyone that any roger pirate besides Ray and lolden are not even in the convo there. So oda saying not anyone means Ray and lolden also most likely can't.
that's why he's the Dark King yeah
What's that got to do with anything?
He's the Dark King cause he was in Roger's shadow. It's an Epithet. That doesn't make him == Roger.
Shanks being above Ray is not a slight to Ray at all. Shanks is mid gen Roger. Ray was Roger's right hand. Not the same thing at all.
