I don't really understand why everyone wants the StG-upgrade for Volks to be a role changing upgrade, when the BAR for Riflemen isn't one either, especially as the effect of the StGs is much less an issue (even compared to only one BAR, which costs less).
I do not know about everyone but for me, for same reasons that i find that LMG on riflemen, buffing SVT's DPS by X2, Penal's PTRS as not good designs.
Weapon profiles and relative positioning.
"Weapon profiles" is the concept that:
A)weapons should be categorized, so that players would not what to expect from their units without having to memorize all DPS curves.
B)Each weapon category should have a range that they excel instead of being about the same in all ranges, so that experienced players could make most out of there units.
Now OKW have a St44 on V.G. with completely different characteristic than the St44 on SP (The Ober ST44 is less of in issue). (The same way that WBP there 3 different types of PTRS with different characteristics)
"Relative positioning" is the concept that:
The player should be able to influence the result of fight by better positioning his units. For instance in a fight Riflemen vs V.G. the fight will go better for V.G. in it long range and worse if in mid range. The ST44 upgrade reduces the benefit the rifles will get by moving closer and thus reduces the players chance to influence the fight. (The same LMG riflemen can use their long range DPS to prevail even if the fight took place in long range.)
