As long as you're activating it on the 2nd hit of a combo (Maim or SS), you should be able to get off 3 full combos and an IB. Activating it as late as possible and having the appropriate SS for your ping is the key to just adding in a Fracture @ 5 Wrath. The pacification is annoying but I like it thematically - you go into a rage and need to calm down for a few seconds afterward.
