Yup… and he did this exact thing again in Wano… He jumped to AdvCoC just to that he can reach YC1 level yet current Zoro probably can’t even knock out fodder willingly with basic CoC
Oda does this with Zoro… Every other AdvCoC user is as Kaido said “amongst the very strongest”, except Zoro, who is a regular YC1 despite having the power of “the very strongest”… and Oda will probably never have Zoro even use regular CoC for fodder control like Luffy despite him having advanced CoC
It’s okay, I know Alabasta Zoro having AdvCoA is a retcon,.. But it’s canon now… It’s been officially stated now that Zoro was the first strawhat to ever use haki and that’s just that now.
