I run a splinter darts build with double snares (Grasp and Wall of Zombies) for elite kiting.
Build here. It's viable early on and only requires level 35, but it's best to use with a dagger and mojo for the fast attack speed and attack speed increasing rings. Mine are 60 intelligence and 15% attack speed each. I also have 11% attack speed gloves. It makes the triple shot splinter darts shoot extremely fast.
Once you get to 40, you could try a
Vision Quest build where if 4 skills are on cooldown, you regenerate mana 300% faster. This lets you spam Dire Bats (40 yard range ones) that do tons of damage. This is what I used up to Inferno. I run splinter darts in Inferno because it allows for more CC and defensive cooldowns. With Vision Quest, you have to keep 4 skills used at all times for it to be viable. In the VQ build I linked, you would keep both pets on cooldown, Big Bad Voodo as well, and use either grasp or spirit walk every time its up.
