A couple suggestions!

1. Remove SL or M12(at least mod them for weaker or higher recoil)
2. Un nerf M4-C and Avtmot Kalashnikova
3. Remove 300+pingers
4. Don't allow trading guns.

1.Those guns are way to strong

2.M4-C was fine long ago. Now its weaker. Also AK has a wierd fire pattern

3. Remove 300+ pingers there really bad and they can't even play.

4.Don't allow trading or else you can get every gun in game. Make a new account then trade. Make a new account then trade. Then you'll have every GP gun.
