There are problem with ST44 that is for sure:
Weapons that are good at all ranges reduce the the need for better positioning which means only on player needs to move to his optimum position while the player with "linear" weapon is better not moving (so that he does not lose DPS on while repositioning.)
That's OKW as a faction problem, faction design makes it so weapons like that is mandatory as they have limited and delayed access to support weapons.
The fact that the DPS in mid close range is concentrated in 2 weapons means that the squad does not lose DPS linearly when losing models.
This wasn't a problem for 20 other squads in game, its not a problem for volks.
Does the BAR has similar issues? yes but one has to keep in mind that Riflemen where designed to carry the faction so they are meant to be and they should be not used as the benchmark.
So were redesigned volks, difference is, rifles are supposed to carry you across the game, volks are supposed to diminish and obers are supposed to phase in mid/late game.
Does LMG34/DP28 have similar issues? Not really because one sacrifices DPS on the move AND close DPS so the unit become more vulnerable to CQB something that increase relative positioning.
Units using these are dedicated long range units.
Volks are not, they are middle point between cons and rifles, being somewhat effective at all ranges.
Does 7 men conscript have similar issues? That is a bit more complicated but the effect is reduced because by the time it become available infatry fight are over and vehicles are involved.
How is 7 man con DPS concentrated around 1-2 models? That was your argument up to this point.
Point here is that relative positing is a great aspect of the game and it effects should be seen in main line infatry.
Volks are supposed to position relatively depending on what they are fighting.
Long range against cons and rifles, CQC against tommies.
The point is there, you just chosen to ignore it.
