Why do you want Zoro to get his ass kicked again so badly?
At least now he is fighting someone who he is capable of beating like King. After his brief clash with Kaido it was made clear that even with Zoro's best shot delivered with a bit of CoC boost it would not be enough to do anything significant to Kaido. Beyond scarring him what did it accomplish? Did it slow him down? Did it weaken him at all?
It's as though your expecting Zoro to magically pull out some sort of power he does not yet fully comprehend to try and beat Kaido.
It's not gonna happen this arc.
