Did 82-84 VP today with a LFD pug. Everyone was CC'ing, silencing, etc and the dungeon was going fairly fast and smooth. The tank was newer and had died on one random pull about halfway through but was doing good overall.
We get to the final boss, Asaad, and for whatever reason the tank doesn't move when the triangle is cast and goes down. I get agro and get taken down to 50% health within a second or two so I vanish. Agro then goes to the hunter who dies (sorry, survival of the fittest). Boss then turns to the mage but I had the healer casting on me so I popped back out with Garrotte and went through a normal rotation and mechanics of the fight but kept Imp Recup up for the damage reduction and the slight HoT to help the healer.
It took a long time to get him down but we did it. A shammy healer, a Mut Rogue, and a (forgot talents) Mage. Credit really goes to the healer but it was pretty awesome to tank down a Cata boss as a rogue. My dps wasn't great (will post some screenshots when I get home) but the fight took quite a while and for some reason my dps started to taper down after a while.
