Things like this is why I prefer Cata pvp to WOTLK pvp. WOTLK had too many classes that could do a lot of damage with little to no skill. Anyone who has died to a shadow priest in WOTLK, checked the combat log, and saw that they were just spamming devouring plague at you knows what I'm talking about.
In Cata, rets weren't as faceroll, shadow priests couldn't spam devouring plague, there really weren't that many classes that were just faceroll OP. It's a weak point of the generally great expansion that is WOTLK.
I will say, though, that the downside of playing a ret in WOTLK is you get very little respect when you win, even if you did happen to do some competent things.
