Quote from FlentyI think with any build relying on sacrifice you will use 2 skill slots with a shared 60 second cooldown.. I mean yes it can do 1300 wpn dmg but it costs 2 skill slots and has 60 sec cd!! Worth it? Not in my opinion.. You will have way too much downtime waiting for cooldowns.
Like I said before this build is not focused on sacrifise. Sacrifice is just there to provide easier time with big bad champion packs. How often do you come across champion packs, I wish they come up as often as once every 60 second...
This build is completely viable with decent damage, best cc in the game (imagine confused inferno monsters, unless they immune), good slow and good distraction provided by 4 dogs when they are alive. What else do you need?
Don't forget the rune for sacrifise and mass confusion also spawns more dogs, so you can detonate them way more often than once every 60 seconds.
