Basically any, honestly.
Ret/Rogue, Hunter/Rogue, Mage/Rogue (to a lesser extent), Lock/Rogue, Boomkin/Rogue (again to a lesser extent), DK/Rogue. I imagine SPriest/Rogue would work though I haven't seen it, but yeah, Rogues can fit into a ton of comps right now. I'd say the only DPS they can't play with is Shamans because they suck, Warriors because of stun DR, Ferals because of stun DR, and WW Monks because they also suck.
I also like how people are still complaining about Disc even though it continues to fall off the higher ratings get. It's almost like it's easy to counter but bad players can't figure out how.
Honestly the most interesting thing to me is how many MW Monks are over 2.4k. I'm not super surprised because a while back I did say I thought MW Monks were strong if played correctly, and I just started playing mine last night and could immediately tell it was stronger than my Disc, but I still expected them to be the least represented healer.
