Dude, zoro is out of the fight. He was overwhelming strong, Impressive feats and did better then most expected. But he went all out, his captain Takes over. Something everyone told you since month.
But with this denial now, you literaly shit on he was able to do, cause it is still Not enough for your headcanon, and obviously he never will, cause Luffy will always be above him.
Your mistake is to take it as Downplay That stronger People exist. Luffy > Kid > Zoro, thats it for now and oda is Position this obviously. Still Zoro would Solo everyone under the roof.
