I really HATE this argument. Like you won't have the enemies names in glowing red letters above their head. Not to mention that unless everyone play naked I don't think it will be that easy to tell a Mechari from a Granok. Not to mention Humans and Cassian. In SWTOR where both factions share all the same race, body and clothing types now they still manage to PvP just fine. Heaven forbid you could actually try to trick someone in PvP, like the spy in Team Fortress.
