I also use

/tar Risen Champion
/tar Chaotic Rift

It might be better to pick and focus the champions, or to try to do a better job of keeping them on the tank, but it's easier for me to just stay on the Knight and let my dps pick off the ghouls in whatever order they feel like.

PS. I wish I still had charming totem in my list.. Just went back there recently for the first time in forever, and couldn't figure out why half of my team was dying to such low level monsters..
