Hmm... sacrifice to regen mana / deal extra damage? With zero second dogs? I like it bro... I wish I had billz to buy some good sacrifice gear.. I can see how this could cause you to rarely die, if at all...
Great build man, I really love to play with dogs+sacrifice, even though I can't afford the cooldown reduction right now.
In fact I got a pretty similar build but more centered around zombie bears than dogs.
I buyed pick up radius stuff and a life leech skorn for pretty cheap, and I spam the bears untill I get low mana, then I get back my mana to full with the mana rune on sacrifice. It works pretty damn well too, the skorn is slower so you don't really need big bad voodoo regeneration at all. Instead I play with the armor bonus on horrify because I need the extra mitigation since I got less than 40k life
(cheap gear and low paragon lvls you know)
