I think it's actually time we get some females who are dressed for the occasion: a vicious, bloody battle in which swords, knives, and various projectiles will be coming at them.
In other words, practical armor and clothing that fits the role. I'm not against the idea of a bit of sexappeal here and there, in a game with this many characters you should keep it diverse. But right now the female champs aren't diverse at all, they're almost exclusively "sexy". Needs more of the other side of the spectrum.
