Depends on your rogues gear. I'm running on my druid as rogue/druid with a decked out rogue (if only we had started up pre CD nerf!). Once your teamwork gets up to snuff, you will find a lot of the "difficult" comps turn into almost free points. Warrior druid becomes eazysauce with no dispel for the roots while the rogue can stick on the druid if he uses his cooldowns well. Rogue/mage can be dicey, but once you get your teamwork up to seemlessly switch targets to get a CC chain running, it's another fairly easy matchup. The problem will be the weird comps will give you trouble, anything with a human rogue will be very rough, 2 humans together will be very difficult. Any ret pally combo will be highly dangerous to you. Shaman/warrior will be either very easy, or almost impossible if the warrior cannot be seperated from the shammy. Once you finally break free of the 1500 bracket, you start running into fewer and fewer of these types of teams, which makes you life much easier.
You will be able to outlast any team other then hunter/disc priest mana-wise or obviously a mirror match so you have a bunch of different strategies open to you. The better the rogues gear is (meaning the more ap and ArP he has) the more and more your druid will be left alone to add CC and dps to the rogue.
Bottom line, I've had a lot of fun playing rogue/druid, moreso then I had with druid/war or druid/rogue/war, and that should be the ultimate barometer of what comp you want to play as, the one you have the most fun with.
