I'll take that in good faith and assume you feel the same about FG-42s and G43s.
In any case, why not just edit the moving stats? Like the absurd 0.1 cooldown modifier on the move could be made 0.5. Movement accuracy to 0.6. Etc.
Most people aren't constantly moving their infantry around.
G43 moving accuracy is too high but this is different subject and F42 is an "elite" weapon but imo it need to get a non linear curve and imo it should be limited to 1-2.
Point here is that BARs makes great at all Riflemen at all ranges and on the move. What I am suggesting is making the weapon good at MID range so that riflemen do not bully LMG grenadiers at far nor will get get bullied by PGs at mid, for a lower cost.
