Here's my setup:

No generator. Just EP and WoL when needed. My main only uses Cyclone Strike and I have a round robin for Inner Sanctuary. Epiphany for Elites to spam WoL. Doing Campaign on Master. I can do it on T1 but is a bit slow and not efficient. Really unlucky with drops, but can't ask much if I'm not doing Torment yet. As soon as I get better yellows, I'll bump it up to T1.

Looting takes so much time when u multibox :/
