Him struggling means nothing if he didn't grow. Luffy didn't learn anything new after fighting Doffy & Cracker. He defeated them with techniques he had from when the timeskip began.
It really doesn't matter if Zoro was secretly stronger than Luffy during Fishman island. It's irrelevant at this point since Luffy is far stronger now than he was then.
Imagine even thinking an underling came out stronger than his captain
Yeah right, luffy always had g4 since TS
Zoro just received Enma and trained
So anyone thinking Zoro was even around cracker/doffy since TS is tripping
Wano Zoro> DR Zoro /TS Zoro
So enough with all the crap "zoro came out stronger than Luffy"
Luffy didn't need any new PU to beat YC dudes like doffy/cracker, he already made G4 during TS
While Zoro and Sanji received PUs for YC tier dudes.
