Forum:KB:Lightsabers and Jedi

The main explanation that seems to be given for the reason mostly Force-users use lightsabers is "Lightsaber combat was difficult to master for a number of reasons, one of them being that all of the weight a lightsaber had was in its hilt, and the gyroscopic effect caused resistance to changes in motion, or built up momentum so quickly than an untrained wielder could lose control of the weapon. " I was thinking, that a lightsaber would lose much of it's potency if not able to deflect blaster bolts (sort of like using a sword against a gun in today's world), and only Force-users can pull that off. Can't that be a simple reason why lightsabers are generally used by Force users?
