So back to comparing apple with pears? A revolver does not CC, a revolver does damage only. A revolver is like shooting with your crossbow, using Shocking touch on the other hand is like using a Taser. It is likely, that your Taser will stun the enemie, but there is also the slight chance, that he can withstand. Same goes for a hook to the chin or if you shoot somebody into his leg, you can't predict how well you aimed and how heavily it will influence him.
