Okay ^^
Luffy has looked deceptively good in this fight. He has done better than more people give him credit for, for example he tanked Kaido's attack, dropped him twice, temporarily (for 2 seconds K.Oed) him
Zoro has looked best on the roof top
-Saved Luffy multiple times
-Showed he can cut fire
-Totally Blitzed Big Mom
-Made Kaido and Meme shit their pants
-Biggest DC Feat in Wano so far
-Also an attack implied (the only attack so far) to have severly wounded Kaido
-Only man to cut through Kaido's scale on top of nullifying Kaido's tornado
-Tanked Big Mom's attack
Killer has just exceeded expectation with Sonic Scythe and Tanking Big Mom's attack
Law is as resourceful as always so he is doing what he can do best
Eustass Kidd --> Oh well He is Useless Midd
So if I am ranking roof top performance on the scale of 10
Zoro - 10
Luffy - 8
Killer - 6
Law - 6
Kidd - 3
