Should spread be reduced?

[Jason]

To reward better aim you need more spread in the center.

Not quite. To reward better aim, you use the guns which were designed for precise shooting: carbine and sniper.

Not quite. Using a Carbine just isn't as effective against a good AR, only an SMG/AR will do it. Maybe Sniper depending on the environment. The point it, a large percentage of the bullets should not be left to chance when one player might be aiming better than another player - and another player might just be loosely aiming to the side of them. Yet somehow the latter player still gets the kill.
