ahh. this argument again. the problem is, rifles and paras can do more dps than anything at long range except obers once you upgrade them with lmgs. the difference is still fairly small though (about 25 dps compared to 28). guards also do about as much damage as lmg grens once they have DPs.
then if you want to talk close range units, shocks obviously win hands down with over 70 dps. lieutenant does about 54 dps at close range. for comparison, pgrens/sturm pios only do about 59. double bar rifles match falls at close and long range and also out dps fusiliers at all ranges.
two weapon upgrades for usf squads is expensive, but the point is there are plenty of soviet and american squads that do about as much if not more dps than axis infantry.
since upgrades are already so expensive, bazookas should be made cheaper. if they were 90 munitions (like i saw someone suggest earlier), i doubt people would get them when you could have 1.5 bars/lmgs for the price unless you made them as good or better than schrecks. making them cheap would make them more accessible and compatible with other upgrades
LMGs are doctrinal and cost 120 ammo for a full squad, I bloody well hope they do some damage, especially considering Rifleman veterancy doesn't do that much to improve their durability. Meanwhile, Obers are non-doctrinal and deploy with their full DPS, no muni required, while having veterancy that makes them enormously durable. US as a whole is a glass cannon faction, that seems like undisputable fact.
And the argument is more regarding vehicles and tanks. Axis tanks generally tend to have better AI than their closest equivalent (P4 vs T-34, StuG vs SU-85, Panther vs Jackson, 222 vs M3/M20, SU-76 vs, what, Kubelwagen?). That's not a balance problem at all, but it makes 57mm have a harder time countering vehicles.
One thing is for sure, in actual gameplay, my own 57mms get decrewed far faster than my ZiS (that may be because those are more durable), and faster than my PaKs. There's also the fact you need to spend a large amount of fuel before getting them (unless you beeline for captain I suppose but that means spamming rifles until
80 fuel) while other factions access it earlier, and as I said getting them delays your actual, solid AT by a pretty big margin.
Point is, US has an AT problem that needs looking at, and in my books that means buffing some of what they have. They're generally the faction with the lowest winrate if I recall correctly, and the fact they have no credible AT response beyond the very fragile Jackson is certainly a part of it.
