Some of the issues I have found running my hunter and Warlock are; 1. When you put pet on aggressive and he engages, if you swap to passive he does not disengage, he continues to fight until the mob is dead. Even after the mob dies you have to hit follow most of the time to get him to come back. Hitting passive should cause the pet to retreat to the hunters/warlocks side. 2. Warlock imp is having a mana issue, which I know has been mentioned in another thread (same for hunter pets (power)), however the damage taken is a little screwy too. I had an Imp totally destroy 3 mobs by himself in melee combat. I like the little guy but he isn't that bad to the bone. 3. When you leave a pet to combat an enemy and run away I have found that about 80% of the time the pet gets stuck in a limbo state and does not vanish. You have to dismiss him and resummons (both hunter and lock) I haven't had my server running long enough to test any further but I will let you know if I see anything else.
