The main problem with MG42 is the RNG of:
1)burst duration
2)cooldown between bursts
Sometimes, the MG starts firing, but because of RNGesus, it stops before if can suppress, if you are even more unlucky they take for ever to fire again. By that time, you either have a frag or a smoke grenade up your ass.
I attest this. I've occasionally seen it suppress stuff out of cover at far range on the first burst, which for a long time I thought was just me seeing things since, well, it usually doesn't. I'd much prefer the burst duration be normalized with cooldown changed in compensation. Make it suppress at far range on the first burst with a longer cooldown or suppress in two bursts with a shorter coolodown, just...make it not a crapshoot.
