Sargeras isnt a bad guy. He only doesnt care about colleteral damage while saving the universe. As long the universe survives life will come back on its own. If the void wins its game over. I guess its slowly time we get defeated by the enemy for the first time. This would bring fresh air if we were not successful in defeat our enemy during a raid dungeon and we are forced to run away. The loot can be described as gathered rare treasures found on argus we can pick up while we are leaving argus with our ship.
