I was doing 10m ICC the other day and our tank that jumped over to tank Mauradin Bronzebeard walked back a little to far and dropped down off the edge. Bronzebeared continued to maintain aggro through the whole fight, but would only throw axes at the tank and wouldn't hit him. I know the fight is easy as it is, but this may come in handy when heroic version becomes available if it still works.
The spot that he got stuck in is circled in the picture. He was stuck in between that little boat and the ledge of the ship. Good luck.
