I've been playing with my Sentry Demon Hunters and added a Witch doctor and they have amazing synergy. Again I use a Chanon Bolter with long fuse and share that key with WD's Piranhado. The taunt actually helps pull the mobs into the Piranhado and keep them there. You can stand right in the middle of the mobs and not get melee'd. Just need one more piece for Full Jade already have Full Pet doctor with Flayer just need Taskers.

I need to figure out how to Round Robin two groups. so that I use One Taunt and One Piranhado each press. Does anyone know how to do that? Is it an action target group or something?

Happy Hunting.
