I tip my hat to anyone that's done it, it's not the solar burn it's the airborne that wrecked me but you know what iam not letting it get the better of me those two fat bastards are going down before reset.
The way we did it (granted we had two hunters) we played ring around the rosey with the middle column to avoid him jumping and splashing as soon as adds popped we turned and each gally'd a door. Then when he retreats it's easy to get through that one. As soon as it says reinforcements just gally the door. When they both show up is when it was tough but we found out as soon as he can take DPS instead of immune both popped golden gun and hit all six shots and two gallys fro our warlock killed him after that it's just clean up adds and the second dude is too easy.
