If there was a female character available and its hit box would be slimmer than the male's, then everyone would play as the female.
Very true , but with a balance in less stright and health , with out the possibility of using heavy weapons , a little more mobility , lets say something like a change from a tank nanosuit , a assault normal nano and a ninja stealth nano . Will be nice don't you think? With the beautiful graphic that cryengine offer ...
i will love that.
I think module customization and weapon customization is pretty enough to build a class perfect just for you. And people argue on every balance aspect in both categories. Introducing one more will just spawn more controversy like: Ninja class is OP/I can't kill tank class, nerf them/assault nano is underwhelming, etc.
A you really offended by the lack of female model? To me it makes sense, since story never hinted that such suit models were even in designs. It would be strange and unusual to introduce them just for the sake of equality.
I think model customization will be introduced someday, either by devs or community. What I am sure of, it will be completely cosmetic, without affecting any physical stats like hit box or speed.
