The easiest way to handle Aurum Vale is to pull mobs back a fair distance. It might irritate the A.D.D. DPS players out there but it will ensure a more healthy party environment, making your job (and the healer's job) a lot easier.

In the first few rooms it is also possible to grab a normal group AND a patrol, which will at least give you the opportunity to build hate and prepare cooldowns. Just make sure your gear/healer can handle it.

Simple answer, but hope it helped. Good luck!
