Well, I guess I was the only person who actually read any of the on screen text when we did this mission because I was the only person attacking the bubbles (as a tank mind you) and of course all the bubbles turn into the jelly things or blobs. Well, once they turn in to the blobs, even if you die, the thing doesn't reset making it impossible to win because you now have a boss and 30+ adds on screen all attacking you at the same time as soon as you attack one of them the next try.

The thing needs to reset once you die. Also, DPS, read and attack the bubbles!
