(I searched but I was not able to find any thread on this exploit)
In Icc the blood queen weekly can be somewhat difficult especially when you're doing all hard modes.
Since the weekly's timer does not start until a player enters the quarter you are able to pull the mobs by having a hunter use eyes of the beast and pull them.
Doing this you are able to clear all trash up to the blood princes (which can be rather lengthy) without even starting the timer.
