Actually Shojindo, i may be wrong about it probably being nerfed*. I looked at some of the upcoming loot in the next ICC bosses:
Heartpierce That's a 1.8 speed MH dagger. The proc has no internal CD, like Bryntroll. In 2v2 a rogue with a priest, you could go envenom spec and sit on an enemy healer. You can already set up 5 stacks of deadly poison, then vanish to get Overkill ticking plus Focused Attacks for mad energy regen. Then this proc as well? That is an INSANE amount of damage from mutilate > envenom > mutilate spam.
A comment by GC seems to suggest that these random procs are the future on gear to make things more fun.
