I completed the disc and shadow one.
Shadow is my main spec, took 2 tries without flask only food buff. 910 - 42 Traits w/ sephuz and belt S2M
Disc is my offspec 907 - 38 traits w/sephuz and bracers, took aorund 30 tries to do it. Did not have a prydaz which would of made it infinitely easier. Big factor in the kill was managing when to use Pain Suppression, used PW: Solace instead of mind bender.
