Soviets are very solid indeed, but the 6 men provides a very minimal to no advatidge. Making it a 4 men mg is no even an option. It gets wiped as often or more as a six man mg then most 4 men mg's already.
20mp price reduction isent much. but it shows more clearly that its a less effective mg. Its not ginna bring the spam back in the slightest.
What I'm saying is - tha maxium would have been 220mp if it was 4-man crew.
But since it has +2 crews, it is added to the squad production cost - thus making it 260 mp.
Same thing goes for UKF. Normal sapper (with 4 men) costs 210 mp. But Sapper Recovery Squad costs 230 mp because it is 5-man squad.
If you consistently gonna say 6 men provides a minimal to no advantage, why not just remove it from Sov's team weapon mechanism? Then we can talk about reducing mp cost for team weapons.
6 men crew + crew merge system makes any - including maxim - team weapon for Soviet extremly difficult to wipe out or at least make it leave the battlefield. Any other faction mg have to reatreat to the base after 1~2 model down, but Sov can just merge cons to the team weapon. So they don't provide window of opportunity to the opposing team,
