For a long time, I've barely used I Eat Your Heart except to kill minions in the open world (not many of those in Khitai...)or the adds at Thoth. While raiding tonight however, I happened to remember someone talking about having it in their raid rotation, and tested it out for a bit. It impressed me a lot - in close to full T4, it did 1800-2200 non-crits and critted for well over 3k. It does have a long animation and a cooldown of a whole minute though.
Seeing as Hell Strikes, and typically HS3 at that, is used so rarely however, I've been considering working I Eat Your Heart into my combo in place of HS3. Since it's "rarely" used though, I imagine it's next to impossible to test this with strawman.
Any of you raiding hoxes got any thoughts of this strange combo? I suppose one eventual disadvantage is that it has fewer chances of incrementing your inferno stacks...
