I genuinely just think Oda panicked at how strong he made Wano Zoro and pulled the entire doesn’t know he has CoC plotline out of his ass to nerf him out of the way until stronger threats arrive further down the line.
The plotline just doesn’t make sense lmao. It’s entirely based on Zoro somehow just thinking that only captains can have CoC when he has literally zero in series reason to think that given the first person he saw use it was Rayleigh. And Mihawk didn’t say it to him either.
The only credit I will give Oda for it is that Nasjuro blocking Zoro in Egghead is actually consistent with ACoC being regens weakness.
