My play group and I switched over to Diablo iii recently. We got to level 50 on this season then all of us decided to switch characters. I went from all passives + disintegrate wizard to witchdoctor, another went from necromancer to crusader, third went from demonhunter to copying my wizard.

I prefer zone control to pets, I'm wondering if a pure control doctor is viable. Grasping hands, mass confusion, hex and horrify or frogs. Anyone have witch doctor experience, and are pets needed?
