Honestly, I think you are making a big deal out of nothing. You are also missing what is probably the main reason for how the characters look.

You think the man has a more pragmatic armor, which is ludicrous. He has horns on his shoulders...you know how stupid this is for actual battle? He is portrayed in this way because he looks badass. That is all.

The point is: the characters were drawn to look cool, and they both _do_. You play the sexist card on the woman, and someone may do the same for the man. Personally, I prefer male characters that look agile, rather than those with heavy armor and burly build/face. There is no reason for a man to necessarily look this way, and I think it furthers the stereotype of what a man needs to look like...well, I don't really think this, but someone could easily make this argument.

You have your right to say you don't like how she is dressed, but calling it sexist is plain wrong. It is a direct attack on the developers, and on those who actually like that type of character design.

I don't particularly love half-naked characters...but I like characters that don't overdo the "pure strength" look. I think she looks like a badass regardless of showing a bit of the belly. I'll probably be playing her, since I like agile-looking characters. If she was wearing a huge armor like him, they would be the same character.

I dislike this type of comment..it's like people calling the books "Dune" sexist. Confuses me to no end, when all my favorite characters end up being female for how badass they are.

Main point: The characters are both drawn to look "cool" and for no other purpose. Neither is a pragmatic design.
