I disagree.
I think Zoro with intel about King’s durability/speed trade off still wins even without COC.
Just instead of taking 15 minutes it takes Zoro an hour or so.
Zoro almost died
a few times against King, and he was fully recharged from the medicine going into this fight, King avoided strafing flying combat because it was too effective and "he loves swords".
You might as well say Sanji could have beaten Queen without armor if fully healed before the fight, given warning of Brachiosnakeus and given the chance to turn it into a battle of attrition,
Might as well give WCI Luffy advantages of not being drugged by a side character, worn down from fighting Cracker, worried about a time limit, fighting in an open area where his speed and aerial mobility can be greater factors, using KKG etc. etc.
Adding hypothetical factors to fights to theorize how some character could possibly grind out a win without their arc powerup is very strange, Zoro/Sanji/Luffy all overcame their fights in victories where they grew past their opponent.
