The fact is Wano was the only arc which Luffy had to hold himself back, in no other arc Luffy needed to concern himself with what would happen whenhe beat his enemy, because the timebomb either was dealt by his crew or by beating the main antagonist, only in Wano arc it's diffrent.
Because Crydo held the entire island as hostage, if he fall everyone fall.
The real reason the fight was drawn for so long wasn't Luffy needed power-ups (ACoC was asspull anyway), it was because Oda needed time for Momo character arc so Oden's son will save everyone lol
