At high elo RNG is unrewarding because gunfights are so close, and the majority of the players have great aim, so the difference between winning or losing a gunfight sometimes depends of how lucky you are with the RNG (the player who gets less RNG wins the gunfight basically).

Of course if you are moving you should get RNG and aim imprecision. But while your character is full stopped your aim should be 100% precise. That's my opinion
