FG42 is too excellent as a general infantry weapon. Very good recoil, large magazine, high damage. Its balance is hard to make.
But AVS36’s competitor in Moscow is only a semi auto with low recoil. (AVS is pretty hard to use in semi mode due to high recoil)
And also, AVS should NOT be in the Berlin. Soviet has so many good weapons came out during WW2, why put this and PPD those prewar weapons in Berlin? And also even later level’s SKS isnt as good as FG42.
But since you already decide to put AVS here. Just give it more ammo, or higher starting levels (with higher preset upgrades)!
