What? Since when was Katakuri called 1st commander? That's not how the BM Pirates are ranked....Yes it does. Marco was first commander and strongest. Same with dogtooth. You're the FIRST commander for a reason
Oda himself said that division number doesn't matter, but I know that you tend to ignore Oda's word. Answer me this question: why would Burgess lose low diff to Sabo if he was a yonko first mate?
