If you learn to control the recoil then this isn't so bad. I've had extensive use and much prefer the Vex, don't get me wrong the VoC is a great gun and in some circumstances is better than the Vex but i'd say 8 times out of 10 I'd prefer to have the Mythoclast. It's only downside is as you point out the damage done to elite's and enemies that do not have crit points, such as minotaurs/ praetorians.
