[Warlock]

I'd agree with the Warlock as a decent choice. It's a rare class and unlike the healers wants much the same equipment on raids as for solo work.

It does vary a lot from server to server though. Might want to check your realm forums or ask in game raiding guild members for what they are looking for. But if you like your Rogue, keep at it - you never know until you try and because many Rogues are farmers the competition for raiding slots might not be as big as you think.
