This would break so many aspect for the game Most players would have at least one sniper with last round. Making head shots in pvp pointless. Most players would have range finder. And considering most people complain about shotgun range this would triple. Only two examples but there are countless others. RNG is the only way to keep a balance among millions of differently skilled players. The great players will be able to use anything given to them. The good players grind out to get a higher chance of getting a badass weapon. The poor players...will be poor regardless of the rolls or perks on the gun.
