I think I would really like to see customizable detailing on armors and weapons, I have heard somewhere that they will be making it possible to combine weapons/armors so that one does not lose stats when aiming for appearence and vice-versa though I can't remember if this is confirmed, anyone know?
Also I think that I would really like to see a ground mount fighting system (since there is already air combat with wings, I don't really see flying mounts to be necessary) because I have always enjoyed galloping around of a wicked looking armoured horse, and being able to fight on horseback, I think would be a really nice realictis fighting scenario additon. Any comments?
