By a combined effort of 16 people, Moment of Silence and Gaia managed to kill the Whale Shark on Dalaran Server.
Has anyone else killed this guy yet? If not, I recommend getting people together and trying to do it. And post here your method.
My method was Kiting. We had me, a Shadow Priest, aggro the Whale Shark with 2 DoT's and just keep refreshing those While backpeddling 2 feet infront of his face. Any closer and he would have eaten me, any farther he would have reset. After about 1 minute of solo kiting and getting Aggro on the Whale Shark, the DPS unleashed, with all Aggro redirect abilities onto me. (Only had 2 Tricks of the Trade).
