We've seen that Luffy is told to maintain his stamina, so Zoro would ask the same of him and not allow him to lose his time and energy fighting King.
Geez why do you keep forgetting, ZORO WAS DOING THIS TOO
Understand? When Apoo was check it outting all over luffy and Zoro, Zoro doesn't say "Luffy you gotta not take damage and save your strength for kaido". Zoro says "we"... he says "we must not take damage" and "we must save our stamina"
Zoro isn't doing what sanji and jinbei are doing. At no point does Zoro prioritise Luffy fighting kaido over himself fighting kaido in this entire raid.
Let me put this in perspective, I believe reopening Kaido's scar requires AT MINIMUM, Admiral level dC. At minimum. I say this because the combined power of the scabbard did literal jack shit to kaido in the long run yet I say the scabbard combined are definitely above anything a YC1 can do. I do not believe Katakuri or Marco or King van do jack shit to kaido. So Zoro reopening the scar is a literal Admiral level feat IMO.
And you are saying Zoro will do this AFTER an extreme diff fight with King? Like Zoro beats king and he has the strength to do Admiral level attacks afterwards? What?
Maybe Zoro doesn't even Extreme diff king then. Maybe Zoro just fuckin mid diffs this man and then goes on to fight kaido. Or are you saying Marco will still be standing after all this to completely heal Zoro to 100% after fighting king so that he can still cut kaido afterwards?
But then this creates the problem of Marco healing everybody now. This means Marco is basically a deus ex machina and everyone from luffy to kid will be able to fight nonstop now.
The cleanest thing to do is remove Zoro's willingness to fight Kaido completely. Like why make this ridiculous situation of Zoro can perform Admiral level feats AFTER an extreme diff fight. Just say Zoro won't ight kaido at all and he'll focus all his energy on king and that's the end of that. Because the alternatives like Marco being able to heal everyone all the time or Zoro mid diffs king are a bit much.
Or maybe you have a better alternative. Let's end this discussion with a run down of what you think will happen now. Power wise and stamina wise. How will Zoro manage to beat king and have the power to still scar kaido afterwards?
