Please note, OP mentions Vicious gear, so we can assume he is talking about Cata.
@OP, as a warlock or priest, you will struggle against rogues. They are a strong counter for you. Once you get your dots up, he will use cloak of shadows to clear them and continue dps'ing like nothing happened. As a warlock, you can try to use a succubus and use seduction when he opens with cheap shot, and follow up with a strong cc chain.
Even still, tough fight by all means against any semi-skilled rogue, as they can always use CoS,Vanish, Smoke Bomb, Prep, etc.
