I was doing a 5 man with a PUG group and i was asked to get my pet to OT. I had bad experiences doing this so I asked the healer to put some heals on him . It was normal ramparts and the healer and me were 70. He said alright and we did the next pull and my pet got no heals, and died. SO I was like wtf, and he said oh I didn't see his health bar, I'll heal him this time. Same thing happens again, and I see that he's doing it on purpose....
So I'm like i'll fix him. I put misdirection on him and multi shot a group of creeps and the healer died. After he died I said oh I thought you were the tank.
Well he got the message and started putting some heals onto my pet
