The comments section is locked on the Update/news post. So we can't really answer the question you asked. What would we like to see in hair styles....

Various braids and long hair styles, for sure.

But mostly what I'd love to see? Hair styles peeking out from under helmets. I hate going bald every time I put one on D: Makes all those pretty hairstyles pointless. And makes the helmets look awkward and uncomfortable. It's a very minor thing and doesn't really add to game play. But since hair was brought up officially, I figured now is the time to mention it!
