And I'm telling you that Mike Tyson is one of the last examples that stand for diversity in boxing, you really should've picked someone else.
That's like me saying Klitschko is a diverse boxer because he used all punches in his fights yet everyone would agree that for the majority is fighting style is one-dimensional and boring. Tyson only delivers knockouts which is why he is more exciting.
Saying that without having seen his go all out. Logias are able to shape their element in all sorts of things, use the ground, create weapons and affect weather. The only thing Zoro has been doing for the entire series is swing his sword as hard as he can, that goes for all swordsman by extension.
Devil fruit users have always been the most diverse combatants.
