ST44 is a bad design and most issue derive from that. On the other hand VG is the only think that hold OKW in the game and the offender on the other side of the fence are equal if not even worse.
StG was just a replacedment for Panzerschrecks. As such, they are timed for when Volks needed a form of AT to handle light vehicles. The implications of the StG timing was never really considered. (As the goal of the time was to break volks schreck blobs, not redesign OKW or fix their matchup against Soviets.)
There are number of change that should be implemented like:
1)Remove sandbags and trenches from all mainline infantry. Using heavy cover should be the exception not the rule in infantry fights and allowing some mainline infantry to have the heavy cover bonuses when and where they want should not be allowed.
I don't have too much of a problem with sandbags themselves. What I do find a bit suspect is the ability for sandbags to be built up against things like VPs. (Although for that IMO VPs should always be rotated 45 degrees so that that their corners are facing the lane/HQs.) The 'free wire' in the cap circle does give a pretty strong advantage to volks and cons. But that's another issue entirely I'd say. Pios building sandbags is just fine I think.
2) Weapons upgrades that improve that do not use weapon's profiles DPS curves or that remove the weakness in range from squad should not be allow especially to mainline infantry.
They should cost fuel. It worked well for vCoH with BARs, (and sorta with panzerschrecks with PE). I think the weapon racks are kind of a nod to this notion. Munitions upgrades should constitute a more role change: AI to AT, rifles into SMGs, getting LMGs (mobile to stationary), etc.
VG are meant to be weak mid to close especially vs Riflemen/Conscript the St44 cover that weakness on the other hand the Riflemen should be weak long range so the LMG should not be available to them either or Penal should not have that much DPS far.
I think riflemen LMG is less of a problem if Volks are getting access to something that gives them a mid-close range edge.
Penals SVTs are broken in that they don't have an aim time multiplier for range, so they rapid fire just as much at range as they do at close range. They are also the only infantry that gets a cooldown buff when moving. (Multiplier of 0.5 instead of >1.)
Imo small arm fires for mainline infantry should be redesigned keep in mind the principals of weapon profiles and relative positioning.
IMO, pre-patch Guards were the most balanced allied infantry. Without PTRS or DP-28s they performed closely to how I'd want a squad of infantry to perform against both axis factions. With PTRS they tended to out-muscle Axis attempts to rush a counter.
Volk with MP40 if want close range combat
Yup. Would've worked out well for the faction. That would also allow for Obers to actually take over a role from volks and give OKW a unit that can flank and try to clear team weapons.
