@Fire Fist:
Vivi isn't a fighter, either. The only time she actually "Hit" someone was the Sniper Pair in the clock tower. Any other time she was helpless.
But she could fight when needed.
@Fire Fist:
First of all, Nami isn't the acting helmsman, Chopper is. Remember how it took the combined effort of Sanji and Usopp to steer back at Reverse mountain, and they STILL broke the helm? Chopper's the only one large and strong enough to effectively steer the helm.
Right, and if Chopper can do in perfectly fine, then there's no reason to seek out another one (When I said Nami was helmsman, I misinterpreted what you said about maneuvering, so sorry about that).
@Fire Fist:
Second, working with stone and brick and steel is very different from working with cloth. You don't ask a welder to knit a sweater for you, do you?
You don't ask someone who builds ships for a living to build a bridge, either.
…Look, I get the feeling that this is going to collapse into a stupid internet argument, so shall we just end it?
