T5 interaction with Kill Command

I'm wondering if the two piece set bonus from teir 5 would heal 15% of kill command's damage?

The bonus says 15% of the dmg you deal, and Kill Command's dmg comes from your pet, but it's a spell you cast.
The pet deals the actual damage though. I dont know though. With the way this class works you would probably get a blue screen of death if you tried it.

Because the damage dealt comes from the pet, and not yourself, the 15% healing is not granted for Kill Command.

However, if you are in a situation where you need to use T5, you're probably also in a situation where you need your pet to keep lots of aggro. So, using KC is still a good idea, but I suppose if aggro isn't an issue, while healing is, it might be best to use all AS and forgo KC.
