Do you have a self heal? I had to resort to kiting to win ALOT of the tougher fights, get aggro and play with Line of sight as much as possible till your pet gets, aggro again, then take aggro back, run...repeat till dead. Since my method is basically me doing the tanking (even though I'm just running), i'd go with my best DPS pet and TURN OFF any tanking Abilities your pet may have (Taunt/Challenge etc.). Keep as many dots up as you can, sneak a hit were you can and keep on the move. good luck.
