Two simple fixes. Step 1) Disable special ammo scavengers in PvP. Step 2) Special ammo only drops from primary ammo kills. Either one would work alone, maybe together is a bit overkill but idc lol. This way you can still spawn with 2 ammo as you do now, but not ape for five years. Only change I would make before doing this - make trace rifles primary ammo instead of special, their damage is laughable next to regular auto rifles.
