the m1919a6 are a lot better than the guard's dp-28. the garand is also far better than the guard's mosin. that dps give dual m1919a6 rifleman the ability to walk over most opposition.
You don't even have to look at the soviet. compare the effectiveness of dual m1919a6 to dual bar.
The penal have rather "normal" dodging bonus compared to the most extreme example.
blob is the easiest and simplest strat to use. it become a problem when the blob have high dps and high dodging bonus.
The same way Rifles are a lot better than old ultimate Volks blob
FRP is reason behind 3/4 of blobs.
Imgaine Ettlebruck Station. Would you blob straight into 2 HMGs if you knew you have to retreat whole way to the base? Nope. But if you do, you gonna lose whole map.
Now, if you know you don't have FRP which saves you from dumb moves, you gonna move careful, recon, etc etc becase you know that each mass retreat means 2-3mins out of game.
Sure, people will still blob even without FRP but then blobbing will be very punishing for them.
