Zoroboys who tought Zoro was Yonko level
Now they have Zoro vs Lucci
Who thought what? Zoro literally met Death after barely scraping through King. Even with the power up that makes him capable of seriously hurting yonko he can't take more than 3-4 clean Kaido or Big Mom hits before breaking down. They on the other hand have durability to take 15-20 shots like that.
Zoro is far from a glass cannon but he is a normal human competing against monsters and he doesn't have the luxury of a rubber God fruit, exoskeleton or cyborg parts.
Zoros AP is ≈ yonko but that in itself doesn't make him into yonko level. What he must do is probably what the other yonko/WSS humans (Shanks, Mihawk, Rayleigh) did - he needs to make sure his CoO is at a level that he never receives more than 3-4 yonko attacks other wise his bones break.
