Build: http://us.battle.net/d3/en/calculator/witch-doctor#egUdZb!bfV!YbZZaa
Since patch 1.03 dots can now crit! More chance wd can do damage.
Use haunt to slow em down and set the spirit barrage a bit ahead of em.
Of course use Spirit walk to get Soul harvest. If OOM use spirit walk w/ mana rune.
What I like to do is set Grasp ahead of em and just spam 3 spirit barrage on top of it. Using haunt can provided little snare before they get to Grasp. Spam leaping spiders while you're at it.
If Gasp is on CD. use haunt and spider for kitting.
In groups you can change haunt with draining rune, and leaping Spiders with fire locust. set your aoe and just walk and avoid everything.
This build has made act1 inferno more survivalable than VQ bears and less boring.
Enjoy
