Do you really want a game where each faction is a shade of grey....
I for one welcome the time when Horde has playable fel orcs, Teron Gorefiendesk Undead, Bloods Elves akin to the ones lead by Kael and Blood Thirsty Trolls/Ogres like in Warcraft 2.
Honestly this game has lost it's way when it comes to opposing factions and the drive to play them. I see threads trying to find morality in the horde when the race would be more fun to play and play against if the dynamic was a race filled with evil mofo's.
I for one welcome more characters like garrosh in the future.
Crossing my fingers for a return of demonic influence to the horde, a rise of Soulless undead(not the treehugging kind we have now).
Or we can kill the only leader that shows any sign of demonic influence and craves bloodlust for a Tauren and we can all sing koom by yah.
Is this the horde you really want to play? Or play against? Might as well remove the Sith from any starwars game since that is pretty much what blizzard is doing to wow with these shades of grey.
