When I did it box - war, ranger, shaman and cleric. The war had about 12.5k ac, I used defensive when I had to because I would agroed a room at a time. Once one clears past first several rooms it gets easier. The named is not that bad, much easier then T8 maybe even T7 minis. At 8-9k ac the Avatars used to tare me up, now a days it is not bad at all. I am not sure if the named hits as hard as an Avatar? Was just happy to win.
