There is a quest in howling fjord that requires you to assemble a abomination and explode it, this quest can be a PITA as you need to kill 20 and can only get 5-8 at a time making the quest take about 10 mins to do (which when powerleveling, is a little long :P).
I found a quick way of doing it is to jump on the roof building and summon the abomination, like so.
Jump down and mash the 1 button once you have atleast one mob near the blast radius.
As you can see, the abom has exploded and the mobs are still alive, this is due to you being on top of the building, causing you, the next person on their threat table to evade bug them.
The thing that makes this much faster is the fact you still get credit and the abom does not "despawn" straight away, if you are on the roof, you can mash the explode button indefinately causing an explosion as fast as you can click the button so grab the center pack, mash the button 4-5 times really fast and quest complete!
to help you out of leecher, nice tip shall use that when I level my druid
