I have two i'd like to propose, i'm a beginner to the game so take my suggestions with that in mind
- Splitter rounds
These rounds are designed to break in half after being fired, creating multishot potential. This is useful to add spread and dilution on firing.
+100% magazine, -10% accuracy, -40% damage, Fires two rounds per shot.
- Featherweight rounds
These rounds are made to be light, aluminium or tin coating etc. They lack a heavy punch, but they increase loading speed and fire rate. I think this would be useful strictly for the reload, which could synergize with other ammo layouts (i.e. something that could buff the gunner)
-20% damage, +10% drop, +20% loading speed, +20% fire rate, +15% magazine
Again, I am by no means an expert...just feel like tossing out my ideas.
