I get that characters in OP can have insane stamina, but its already been established that zoro was immobilized after hakai, and he's now taking twice the damage on top of what he took from king. Its already been established that zoro is basically immobile.
So can a single ZKK supporter tell me how this is going to be rectified? Marco can't just heal him because 1) marco's flames drain stamina and 2) Marco has never used this degree of healing on anybody other than himself. Surely if ZKK were to happen, zoro's revival surely wouldn't be reliant on an asspull, now would it?
What's different about this time compared to every other time is that Zoro still has unfinished business/plots in Wano, and if you don't believe that he does, I honestly don't know what to tell you.
If Hyogoro's comment about Luffy being like a "guardian deity" or whatever he said and Who's Who's comment about the Gomu Gomu no Mi received immediate payoff, I don't see how the same Hyogoro (and Kawamatsu) noticing Zoro's resemblance to Ryuma/Ushimaru and commenting on Zoro's "fate" being tied to Wano won't receive a similar payoff
In fact, we've been teased on black blades since act 1 or act 2 and we haven't gotten any development on that yet.
You'd have to think that Zoro will be dying/unconscious for all of this lore that pertains to him, and I can't see that being the case. Besides, there should be hardly any time left for Zoro to be out of commission for another arc. The end of Wano will likely trigger a worldwide chaos that puts the Straw Hats at the center of everything, I doubt there will be much downtime for the Straw Hats
