I have always used Scholo and just did a simple room by room pull, I used a druid using swipe which kills everything really fast.
Rattlegore is not worth doing IMHO unless you want the shards or drops.
I normally just pull the first 3 rooms, each time moving my lowbies up to just outside each door.
Also worth getting the quests as they get a ton of XP and real easy when boosting.
