Cata - End Times Heroic

[Mortiasis]

Those of you that have completed this instance, how do you handle the Tryande fight? I run with paladin with 3 elemental shamans and 1 resto shaman. The swirling ball of death keeps me silence and does tons of aoe that I cant keep up.
My dps is decent, its an average on 19k on each elemental shaman, but the closet I got him is around 50%

I use a Blood DK, Lock, Hunter, Ret pally and a discpriest.

With ISBoxer I have "ranged move forward(shift + w), ranged strafe left(shift + q), ranged strafe right(shift + e)" keys.
I drive from my healer and stay at 35-40 yards max ranged. When she does moonbeam I strafe left, next moonbeam I strafe right, When the silencing orbs arrive I move forward 5ish yards out of its pathing. When the next spawns same thing. When the first despawns and the third spawns I use my ranged follow key(Shift + F) and move back to max range. Rinse and repeat. Hope this helps!
