Which Captains? Luffy? Neg diff? Kid, around same diff as Luffy, Law? At best push him to mid diff based how strong Law became.
Zoro would do similar thing to Doffy, he was already pre wano> and with Enma and now adv CoC, Doffy would get rekt by Zoro very hard.
Hmmm are we really gonna compare what Zoro can see to what Kata can see ahead in the future? Kata is and will always have better reaction speed than Zoro and honestly most some top tiers(not including those who have FS as well obviously)
zoro still has to get used to it
he pulling out too much haki not using just what he needs
hes got to be more efficient with it which am sure he will get better with moving foward.
improvements to observation hopefully against shiryu and he will be a complete top tier fighter
the irony is he is closer to the "hakiman" image a lot of shanks fan are allured to . no df or unnatural enhancements.
