Swap the ZH-29 (BR 4) with the VG 1-5 (BR 3) and move the VG. 2, Gewehr 41 & Gewehr 43 back one BR (BR 2, BR 2 & BR 3).
This would make the ZH more viable and make the VG 1-5 appear in Berlin more rather than earlier war maps. Also the VG 1-5 slaps as a rifle with it’s 30 round STG mag so no idea why it’s in BR 3 to begin with.
To summarise here is the order of unlocks I’m suggesting.
Armaguerra Mod. 39 (BR 2) >>> VG. 2 (BR 2) >>> Gewehr 41 (BR 2) >>> ZH29 (BR 3) >>> Gewehr 43 (BR 3) >>> VG 1-5 (BR 4) >>> FG 42 (BR 5) ect.
