If people ignore Sanji was injured when Sanji fought Vergo then yes that will make Vergo stronger than Doffy because healthy Sanji cracked his leg against Vergo but not against YC but if people agree that Sanji was injured which is the reason Vergo looked superior, then that's not the case.
Inconsistent right if people ignore the context that Sanji's body was damaged before he fought Vergo.
The problem isn't even with sanji but the inconsistency with luffy,law and the others..
Law cut down vergo but is weaker than luffy who ragdolled doflamingo and we know law was no match for doffy..
So if vergo is yc1,then law is yc1+,doffy is yc1++ and luffy who is even stronger than that will be yc1+++ and yet luffy had issues against cracker and was no match for katakuri..
So does that mean cracker is at least yc1+ +? And katakuri who was beating luffy easily is low top tier or something??
Too much inconsistency for Vergo to be yc1 lol.
