Diablo III- Skills Article CXXV: Witch Doctor, Theorycraft Three- Midget Storm

This build takes advantage of Fetish Syncophants and other Fetish-oriented skills to have a lot of minions running around doing their own independent things.  This allows you to also benefit from Vision Quest easily, and so other skills are selected on the basis of two things- having four hotkey skills that are cooling down most of the time, and generating even more creatures to wander around independently.  This means not only Zombie Dogs, but also Creepers, confused enemies, and other independently acting skill effects.

Primary Skill: Corpse Spiders (Leaping Spiders)
Secondary Skill: Firebats (Hungry Bats)
Defensive Skill: Summon Zombie Dogs (Final Gift)
Terror Skill: Mass Confusion (Devolution)
Decay Skill: Wall of Zombies (Creepers)
Voodoo Skill: Fetish Army (Legion of Daggers)
Passive Skills: Fetish Syncophants, Vision Quest, Tribal Rites

The choice of Fetish Syncophants and Tribal Rites is fairly obvious- the Syncophants and the Army, which benefits from Rites, both generate Fetishes.  Leaping Spiders is the most potent of the Primary skills available for this setup- not because of the damage, as Plague of Toads deals more damage a lot of the time, but because the spiders will leap to new targets as soon as their current one is dead, and the skill is so fast and low-cost that while Vision Quest is refilling your Mana pool you will wind up generating a lot of not only spiders but a lot of chances for more Fetishes.  Summon Zombie Dogs is chosen for two reasons- first of all, while the Zombie Dogs aren’t very durable at later levels, not only is it still three more bodies on the field but also it lets you tack Final Gift on, which actually rewards you for letting the Dogs die.  This also allows the form of Mass Confusion that generates even more Zombie Dogs to be used, as it kicks up more dogs (which means more health orbs) and turns some of your enemies into temporary minions as well.

After all that, the use of Hungry Bats is almost an afterthought, but it does give you a good channel to put your massive Mana fund (thanks to Vision Quest and four cooldowns) into, and since the bats home in on targets, you don’t even have to aim- and while the effect isn’t technically spawning minions, it certainly looks and targets as though you were.

You may find that this build, thanks to the sheer amount of stuff it generates, is not so great with many parties in multiplayer games- but if you’re part of a group that lacks a melee character, you may find that same problem becoming a benefit instead.

If you find that the multitude of Zombie Dogs and their health orbs aren’t to your liking, you can always go with Hex (Hedge Magic) and Mass Confusion (Mass Hallucination) to heal, disrupt an enemy, and flash out extra damage while still having the four cooldowns to trigger Vision Quest and also spawning things all over the battlefield.
