I'm level 50 in act 1 hell using witchdoctor and I'm not using any of this nor did I even think of any of this, I have died over and over and over and not being very useful, now that I read this I'm going to try it out, thank you.
What I been using is this
poison dart ( flaming dart )
grasp of the dead ( death is life )
zombie dogs ( final gift )
mass confusion ( paranoia )
acid cloud ( slow burn )
gargantuan ( restless giant )
if I see any enemies coming I cast grasp of the dead, use the acid cloud, dogs run in and gargantuan runs in and I stay back shooting the flaming darts, it's the only way I knew how to play, and I can honestly say this build sucks,
so seeing what you wrote, I will def give it a try, thank you
