Put its damage down, more hipfire spread, lower fire rate, more recoil for ADS.
In short, kill the gun.
But they probably won't kill it because its too popular. But I hope they do.
make it so anyone that uses the gun gets instabanned and forced to wear a "i use easy weapons" emblem for the rest of his life.
Make it so only people in bootcamp can use it.
Or throw it in the valcano from Lord of the Rings
I don't like it, the mag size is the the biggest thing that is wrong with the gun, 50 bullets for an SMG with no recoil by default, a weapon that needs no speed upgrades such as quickdraw handle or the stock.
