This fight is incredibly tightly tuned.

There is very little in the way of new mechanics here. It's just increased damage to the point where the margin for error becomes very very small.

First: tanks should guard healers. This reduces the chances of the adds nuking down your healers the second they spawn (tanks will still need to taunt the adds when they spawn to reduce damage.

Seconds: DPS and Healers should try to make their blue circles in mass barrage as tight as possible. You do not need a full circles width.

With blue circles, you will get 4 (sometimes 3 or 5). If you drop the 1st one, it won't start dealing damage until right before the 3rd one drops. This means you can drop 2 right on top of each other, move JUST outside the circles radius to drop 3 and 4, and you're done. Your 4 circles should all overlap. If you spread the circles out nice and far, you're going to run out of real estate very quickly, and extra damage in the mass barrage phase is a death sentence.

Best of luck.
