Me and a friend dueled each other a few times but I was incredibly amazed with his DPS. He made Mistform's mitigation in PvP look like nothing, he had to have so much damage!
In reality he didn't have the damage I was being led to believe. I told him to stop attacking me and he did, and then I had him hit me with Blastbones in Mistform and outside of Mistform.... same damage.
Blastbones, a player casted ability, does not count as player damage and thus ignores the damage mitigation of Mistform. This change to Mistform has actually managed to kill the ability in PvP as well as PvE. I wouldn't be surprised if the other pet attacks that don't count as being done by you did the same.
Edit: And the other pets do go through Mistform as well.
