It's true that Luffy had plenty of assistance and would've never won against Doffy in DR.
And I'm all for Doffy >= YC1
but the way Doffy jobbed to boundman is just bad whereas with Katakuri it didn't even matter that he used G4 (before he mastered FS)
I know if Oda reintroduced Doffy in the story, he'd be much stronger though...
Oda said Luffy would have one against Doflamingo without help so it rmans Luffy was really OP.
Luffy also fought for 24 hrs constantly in the colosuem using haki and stamina and ran all day before getting to Doflamingo.
Luffy was very strong post timeskip. We are seeing that now.
No wonder Rayleigh was confindetn in luffy post timeskip.
Luffy was already at the top tye moment he came back from timeskip.
Even Fujitora got injrued against dressorass Gear 3 with reguler armament haki.
Gear 4 without advanced haki was Yonko level in terms of physical strength as I thought.
