Pretty simple, strong pets with Jungle Fortitude and Zombie handler with Bad Medicine for reduced enemy damage. Lots of EHP. Strong single target poison attack. Medium damage medium AE poison attack. Low damage high AE poison attack. Could swap Mass confusion for Horrify. Thoughts?
Definitely looks like a very solid build, though I'd swap mass confusion for horrify, spirit walk or grasp of the dead. Any one of those gives more reliable cc/escape capability than mass confusion. I'd also consider the big stinker rune for the gargantuan which will result in more damage than the cleave and provides more poison for bad medicine. Finally, you may get more survivability from leeching beasts on your zombie dogs than you get from life link...at least worth checking out.
