How good is crippling strike in this build? I have a 11Rang/6Monk/3Rog version of this build which I love and have taken crippling strike but am wondering on how useful it is. Even with a high rate of fire mobs just seem to die to fast for it to come into play, only orange nameds seem to enough hp for it to matter on and since they can be paralzyed it still seems of limited use.
