Death grip rotation on the 4 followers plants the mob directly in melee range for everyone. Chains of ice are cast from another alt and strangulate if one of them have it available, if not I mind freeze casters with the main.

4-5 icy touch hit next depending on if I had to mind freeze or not.

Obliterate kills any regular mob that survived the first hit, on elites I use death strike first. That 3 round spell rotation will kill pretty much anything at level fairly fast and keep everyone topped off on health. I'm working on getting better control over their attack rotation but it hasn't been necessary yet.
