Back to the missing transformations dilemma, I think I'd prefer that for some characters. I don't wanna see Frost take up more than 1 character slot, and I wouldn't be upset over Baby not having his first two forms.
The reveal that the world used to be continents was enough for me, but I get it.
I think the important thing about this is mainly that the entire population is privy to this information, and what consequences arises from that.
One Piece really doesn't lean that heavily into it. Yes, matchups can matter to an extent but the scaling is generally straightforward. It isn't HxH or JoJo.
If we go solely on hypotheticals I can see Law faring a lot better than Luffy did against Cracker, perhaps.
