I know, it makes me sad 
Rogue in general is great into boomy/dh, though (specifically boomy). Sub also farms. Boomy doesnt have any reliable non-casted peel on a short enough CD to disrupt goes, so sub+mage/lock/hunter can just murder your DH or healer very reliably and just save CS for boomy on the go.
Outside of rogue, war and destro do pretty well also, but the DH/Boomy can definitely win those MUs.
