Currently in enlisted MGs are just bad. They are not satisfying to use, nor are they realistic.
How it is right now is that they have 0 weight to them, dispersion is way too high, bipods are still very broken.
1. Heavily decrease the dispersion of MGs al together. Currently they are almost unusable at range
2. Add weight to them. Now what i mean is make them more realistic. MGs arent light, the average soldier cant ADS while not mounting the machinegun. Make it so if you do not mount your MG, you cant ADS and would basically have a more spray, stock under the shoulder hands on a bipod (MG42/DP27) or a beil (1919). Aiming while not braced would take around 0.5 sec to prepare for the firing position.
While braced your movement speed is very slow
Something like this:
HLL:
BF5
And yes, there could be a perk, that requires 15 stamina (heart) You would be able to ADS with an MG, but not for a long time (Up to 10 sec, depends on the vitality points)
This only applies to heavier MGs. These being MG13, MG34, MG42, ZB26, Breda mod.30, 1919MG, DP27, DT29, all Japanese MGs
The rest can be used as normal such as the BAR, Bren
3. Better bipods: !!!
This is together with 2 would make MGs the most badass, realistic weapon in game. Fix the bipods already. And also do some extra additions:
Add a command for your AI squadmate to be able to mount an MG on their shoulder
4. Add different magazine sizes to be unlocked
Allow us to use larger ammo capacity belts for our Belt fed MGs such as MG42, 1919MG etc. Such as 50, 100, 150, 200. This is balanced out by 2 and 5
Bigger belts would increase the reload time, and decrease movement speed making you slower
5. Add a overheating mechanic
This would balance out the larger belts. This would mostly effect the MG34, MG42, but a 1919 can also overheat from intense fire.
If a weapon overheats it is unusable for a short period of time, like the MGs on tanks or builded ones. This wouldnt effect MGs that dont need to be braced (2) for ex - Madsen, BAR, Japanese MGs due to low ammo count. etc
Later on barrel change mechanics could be introduced
6. Realistic rate of fire
This is just embarrassing
Make the MG42 ROF 1200 RPM
I think that these changes would make MGs better, and more balanced, realistic
