To all the WDs trying to survive Inferno, unless you're in Act 1 (and even then), just drop the VQ+Dire Bears combo, it doesn't work. The bears are way too short range and you end up just popping all your cooldowns for VQ, throwing any survivability out of the window.
It's all about kiting, Splinters, 2.00+ Attack speed, 20k dps and some items with about 10-20 +mana regen. Here's my build:

Here are my stats :

Always keep Grasp up, 80% slow is absolutely huge. That + the wall of zombies and you're in kiting heaven. Not only that, but Grasp and the wall of zombies deal a very impressive amount of damage while you Splinter them like a machine gun. You can switch the stats between more resistance or more health, but I like the resistance. With the Splinters being able to hit monsters not even in the screen, you must try never to get hit. If they get near you, pop Spirit Walk and run away. It's super refreshing not to have to worry about the cooldowns being up like with a VQ build.
The AWESOME thing about FS is that because your attack speed is so ridiculous, you almost always have fetishes summoned around you and they're by far the best pets a WD can have (dogs and gargs being useless in inferno), since they deal great damage and can distract+tank monsters for a while. I usually run around with at least 3 fetishes at ALL times.
