Agreed. Perhaps there can be a fix to the firing. Being able to adjust what the actor targets. If the actor can see the head, and only the head, then we should be able to target the actor bone "head" (I dont know what your doing for animations and labeling, etc), or shoulder, or chest. Arm or hand hits could disarm, whereas leg hits could slow or disable.
The particulars, IMO, could wait till things are worked out a little smoother, but the targeting body parts seems entirely plausible.
