Why are you downplaying nami feats as if she wasn't the key component to defeating cracker without her luffy would have not been able to fight for as long as he did as the crackers were soft enough to eat thus replenishing his stamina each time he ate 1 which he did so for 11 hours all thanks to nami. In a fight damage is not the only thing that applies strategy is also a thing as well which nami did effortlessly
This is literally law debate all over again how ppl underrated his involvement with dofflamingo' s defeat
