Has anyone tried a Mutilate spec with and without Imp Poisons and noticed much of a significant difference in proc rate between the two? I understand the importance of a poisoned target with Mutilate, but 5 points seems like a lot for a talent that gives you only a 10% increase in your chance to poison. So does that mean only 1 in 10 mobs will poison more quickly than normal? Wouldn't you rather take a guaranteed increase in damage with Vile Poisons? Or, maybe some other combination of points in this Assasination tree: http://www.wowhead.com/?talent=ihe0kE0sizVo to get the 41 points?
