A severe nerf for the Red-34 because everyone uses it and it's so overpowered
More power for the Aresk-07 because it's the convention for Modern Combat that bolt-action has a one shot one kill mechanism
Make the KR-200 fully automatic and make the UFIA PSD-2 a burst action because a UFIA has high power and I want to see the AK types fully automatic like the KT-44. And it's the convention that AK-47s are always fully automatic.
Add a tier 6 gun for every class
Make the sidearms customizable between weapon types; they ruined it when we can only select pistols as sidearms.
