Funny about all this is that for the story as it stands (Maybe the whole “tyrannical light”-thing is a big story setup for later) is that it’s utterly unnecessary, all the Horde would need to recruit the Mag’har is tell them “You want to fight? We got a fight right here!” and orcs being orcs, they would leap at the chance! :3
But now the Alliance story is completely warped, just to give orcs a reason to hang out with other orcs, yay...
