Seen some great ideas here. but also some less great ideas. val'kyrs are angels of war. and there arent many of them if i remember correct. also i think sylvanas is the only one who would accept them. and for the four legged races. that might have been cool in vanilla but with flying mounts it just wont work. now as most people say. ogres are obviously for the horde. there are already some clans working with the horde. and they are not pretty or very smart. but its the horde we are talking about. we dont wear fancy suits and drink tea. And if lore allows Nagas to join alliance then i cant see why they cant be playable. for the legs and boots they simply make them skirts or make them sit tight around the tail. and the boots become rings at the end of the tail. and for the females with 4 arms. upper arms for melee animation and lower arms for casting animations. sitting/mounts. simply make them sit alittle sideways so the tail hang on either the left or the right side.
