WOW GOLD-Rogue/Mage/Priest 3v3: See above

Priest/Affliction Warlock 2v2: You are starting to see a lot of these pop up on many battle groups because of the raw damage output and survivability that a warlock has in full furious gear now about cheap wow gold. Many warlocks can push over 2500 damage without even using fel armor, and when a disc priest is specd for damage talents and glyped for smite, this comp can easily outlast most healer/dps teams, especially with double mana draining abilities. I have also seen this played quite successfully with a destruction warlock instead of affliction, turning the team into a cc -> burst comp, rather than outlast about World of Warcraft Gold.

Combat Rogue/Restoration shaman or Disc Priest 2v2: This seems to be the new fad and it is definitely effective. When specd for full dodge and parry talents, combat rogues are incredibly difficult to toe-to-toe due to having over 35% dodge unbuffed, 10% parry, riposte, unfair advantage, short cool down evasions, blade twisting, combat potency, and reduced damage taken while stunned. If a combat rogue catches anyone at around 50% with their healer ccd, one killing spree combined with a slow off-hand weapon swap can easily drop them to dead unless an emergency cool down is used to get cheap wow gold.

Rogue/Warlock/Shaman 3v3: Similar in some regards to RMP, RLS approaches fights a bit differently but has the same principles. You can both tunnel vision one target for a whole game or swap around a lot depending on who is in a bad spot or who does not have their trinket up. One good burst combo with the warlocks chaos bolt and shamans lava burst to get cheap wow gold, not to mention the rogues damage, is enough to 1-round almost any class that is not healed immediately. Although not quite the easiest ticket to the top of a battle group, it is certainly far from challenging to play about cheap wow gold.
