I don’t have the problem with balancing the weapons (although to be fair, the AVT-40 and AVS-36 should have more recoil than the FG 42 - it’s the nature of these weapons’ design). What I do have problem with is the fact that it’s hidden.
Besides, the AVS-36 and the AVT-40 should be implemented the way they are in Stalingrad - for assaulters (and maybe engineers) as a counter for the StG 44 family.
And as for the FG 42, it should be implemented in a different way, maybe even as a machine gun. I would really dislike that (as it’s not just a machine gun), but if they did it with the Johnson (which was used by like half of the teams, not just as a support weapon) then I guess they should do it with the FG 42 as well.
