Same here. Using mage in pet tank role on brothers island and she ran right on top of the mob. Worse than that, in a Degmar HA, she ran up to the mob and got hit so took off running and trained the whole group.
I know some of these things are designed to make it easier to fully afk, but a lot of players that I know just use Kiss to box their 2nd and 3rd class. If you are not fully afk, and you want to box a mage in pettank role in say... Degmar, the mage will inevitably be training the group if she takes a little hit. I finally just took the logic for I GOT HIT out/modified it.
