in my experience, the lack of suppression isn't really a problem, in the beginning anyway.
In the early game, the volks with sturm is capable of fighting against conscript and rifleman without the need of a hmg.
The problem is when the conscript and rifleman reach terminator vet and completely outscale the axis infantry. It is more of a problem with the terminator vet.
The other problem is that LeIG had become reliant on its suppression. It needs a ROF and/or AOE buff in exchange for the suppression removal. It also need to do damage to garrison. The allies all have hmg the OKW need to deal with.
Lastly, the flak ht is technically the OKW's suppression platform, it just have crap survivability.
