I do wish the Xaela were a little different from the Raen.
Like the way they move and stand, it just seems very proper. The way they bow and do their animations just doesn't really fit Xaela as well as Raen. Just a pet peeve, since they are supposed to be more Mongolian when the Raen are supposed to be Japanese, as well as being more Tribal and brutal.
they just seem a bit more cutesy then their original art and it feels like they deserve a bit more animations. Since they added more space to the game I don't think it would hurt to let both trade their horns now for different ones.
Also scale colors would be nice to, of course you shouldn't let Xaela have whiter scales but probably just darker colors whilst Raen can have lighter colors. ((I still believe that we should be able to switch our horn styles...))
