we killed it on sunday for the first time and what we did was have everybody stack up on a world marker during the kiting phase so people would not be spread all over the room at the end of the phase, then i put down a new marker where we wuld move as a group towards and stack up again so we could keep aoe healing.
we did the fight with 3 healer 2 tanks and 5 dps(of wich were 2 melee, a hunter and 2 casters) and just have the 2 melee and the tanks on the jailor, i would usually switch off the jailor when it was around 10-15% and begin attacking the boss with ST and when i could i'd attack it normally from the side.
for reference i ran with burst of speed(wich i have taken a real liking to :P) and shuriken toss (used the CP for SnD or rupture).
we got him down around ~10% in the kiting phases, also we had around 20 ish stacks on the 1st burn phase and the 3rd one because of 3 minute cooldowns being back up, only got around 10 ish stacks during the second burn phase and the last one (fire) we almost completely skipped and went in to a kiting phase again to avoid most of the fire :P
anyway i hope this helped a little bit (and sorry about the longish post :P)
