I just did this on my lvl 59 Blood Elf Beast Mastery Hunter. Unfortunately, a friendly Night Elf druid decided to help me, and things kind of went downhill from there.

She'd mind control me, I'd cast "Scare Beast" on the bear-form Night Elf, Night Elf would go fleeing into a group of adjacent mobs, aggroing all of them, boss would heal herself, my pet would attack me. Somehow the word "clusterfuck" seems inadequate.

We managed to win, but the whole thing dragged on for about ten minutes.
