The base these day's is usually Flesh Golem, Bone Fiend, Blood of the Master, and Verrata's Aura (for when you die). Then there's some flexibility, but missing any of those skills makes it fairly abnormal.
N/Mo is very popular. Usually spend some points on Healing, and take Heal Area and Healing Breeze for keeping yourself alive.
Note that these are usually dedicated minion masters. They don't have other defensive or healing skills, and are mostly useless for anything else (which is usually fine).
