I don't pull all of the the down stairs area because casters suck.
And for the ones pull, I break LoS and pull them up top and behind the door.

After that, I kill each pack, especially the warlock summoners. I once pull the entire room, and OMG, I had massive adds from the summons.

I also single pack pull the ones with teachers.

I pull the entire room with the little flying dragons, all the mobs in Rattlegore's room.

I then do the boss area one room at a time. one pack at a time on the top room with casters.

The bottom room with casters aren't bad to one pull.

I think Strath would be easier, but I hate the eye and gargoyles. I did not try the live side yet, it may be better.
