Actually this is an interesting and incredibly annoying comp I ran into a few times in 2v2 about wow gold. With the way HoTs and lifebloom in particular are now, the resto druid can effectively keep the feral druid alive through any healer/dps team while staying in cat form the entire time about wow gold. After several minutes of this, the resto druid will eventually innervate himself and then if you can even manage to OOM him again, the feral druid has yet another innervate for the resto druid, basically giving the opposing team roughly a 3-minute window to kill something in before the next innervate comes up unless you manage to land a good cc chain or unhealable burst, which is not the easiest task when going up against double cyclones, double roots, feral stuns, feral snares, etc.

Death Knight/Holy Paladin/BM Hunter 3v3: The "eMazing gaming comp" is pretty much as easy as it gets, especially as BM, for a hunter to get high ratings in arena right now. While some teams are actually easier to play against as survival to get cheap wow gold, being BM allows this team to freedom the DK almost every game and push for a super aggressive kill right at the start and even if the other team survives the initial burst, the hunters BM only takes a minute to come back up for Round 2 to get cheap wow gold.

Hunter/DK/Ele Shaman/Priest/Paladin 5v5: Because hunters are countered by a lot of setups right now in 2v2, the next best ticket for high ratings I think would be from running this 5v5 "nurfed comp." The premise behind it is actually very simple: the hunter and ele shaman assist on the same targets doing the same swaps together while the DK can either play interrupt on the healers or train the same target for maximum faceroll about wow gold. With ebon plague on everything from the DK, the shaman and hunter (assuming survival) will be doing large amounts of burst with this setup.
