Did one TW dungeon on 5 characters yesterday, just to get the quest item. Pit of Saron every single time, it's like the dungeon is guaranteed to be the first TW dungeon of the week for me. The dungeon was 10 times smoother as a dps or tank than it was as a healer, as a tank you can manage the bosses/trash properly and as a dps you can just blow everything up before everyone dies if you have the right gear, as a healer you're really just stuck relying on other people and it sucked big time.
