The new Perfect Agony is antisynergistic with the crit+DoT clusters on the tree.

The thing that confuses me most is the notable adders touch the wording on it says "Critical Strikes with Daggers Poison the Enemy". From what I gather that means it makes it so critical strike can poison the enemy? But that interferes with Perfect Agony and it also makes you think it makes it always poison but it doesn't provide the chance just like re worked assassin doesn't. I'm so confused looking into this.
