I mean, I like Hickman's definition and it's fairly restricting in a way that I agree with. My only real issue with it is some stated examples (Like I got no idea why Hope is in the spot that Rogue should be in other than because they don't want to bench Rogue with Resurrection duties.)
Like Eva's never gonna be the top time person cause Kang does it, but more consistently, more varied and all around better
Johnny Storm is always gonna be a wall to any fire user.
And let's be fair, who the hell is out-punching the Hulk on a consistent basis?
