Alright, Me and my guild found this out accidentally. As soon as you enter AV get everyone to get to the last boss as soon as possible, (If you don't have any botters) Then as soon as your last man is there go inside the room and get one person to kill a person from the opposing faction. Right when he gets rep run into the boss room. The boss should respond and start to attack. Correct me if I'm wrong but I believe this still works. Good Luck. For another quick way to kill the boss quit WoW. Its a waste. Thats all
