No one has aided Luffy in fights more than Nami.
Oda isn't that sexist (he is a little, but I think he tries hard to write strong women). He just realizes women don't need to beat people up in order to be strong. The people who act like Nami is a trash character because she isn't attacking people and beating people up all the time are the ones who are weak (mentally).
