Kill Warlock/Pet then Shaman. To me this feels like the easiest team to fight. Depending on the warlock, your target selection is simple. If the warlock has a felhunter out, you will almost certainly need to kill the pet first, especially if it's a SL/SL lock. When killing pets, taunt/challenging shout/mocking blow works very well and always, always remember to line of sight of the healer. If the pet stays on your druid, have the druid run to you and you should both be LOSing the Warlock. The druid should Feral Charge+Bash the healer when either the pet or the lock is almost dead. Don't forget to watch for mana tide and kill grounding totem/tremor totem if you see it. The most important thing you can do is pummel fears, so save your pummel cool down for that purpose.
