The new passive Creeping Death opens up a lot of possibilities for a DoT Witch Doctor build, particularly one revolving around Locust Swarm, Haunt, and Piranhas. It works great against hordes of whites, elites, and bosses.
With more specific gear, you’ll be able to 1 shot an entire screen of white mobs and destroy bosses by casting 3 spells and then just running around. You’ll also never run out of mana, no matter how much you cast.
