Izi is the fire spec of mine basically, he has sacrifice so he can sac his imp for 15% more fire damage and im pretty damn sure he will have demonic aegis to get 30 more dpell dmg
I'm gunna go this spec when i get a new chest, imo i will need more fire dmg than i have to make it worth it.
I dont know the exact talents ghe has but i know that its an imbah dps spec, a decent amount of hit and crit with a healthy amount of damage its pretty darn nice =P
