Tell that to a rogue who PvPs a lot --- at one point rogues were dominant in PvP, but now they are disbalanced lower than they should be --- rogues regularly get pwnd by warlocks, shamans, hunters, druids, and warriors in one-on-one (unless they have M4D FLYING G0UG3 SK!LLZ like Rueage). This is simply borked because Blizzard has insisted that each class is supposed to be balanced so that it can own two classes with ease and be owned by only two easily.
At one point any run-ins with rogues would leave me dead (druids are supposed to be one of the 'with ease' classes for rogues) but nowadays in PvP i've frequently done two rogues simultaneously by myself. I think it is about time they got a buffing.
