This fight is from the treadmill (or conveyor belt) perspective. We typically use just one belt group using hunters that can disengage onto the conveyor belt without having to use the pipes. The burst cooldowns such as Bestial Wrath line up well with the timing of new belts. With multiple hunters we could also use a variety of pets for appropriate buffs and debuffs. Hunters can also deterrence the ground fire damage from overcharged laser turrets.
This belt strategy (and the fight in general) is incredibly unforgiving.
PS: I apologize it's not the HD quality I typically do. The slightest mis-maneuver and I was dead. Frapsing at "Full-size 60fps" was too laggy for my computer in a 25 man raid. I had to move it to "half-size" at 30fps. My apologies.
