If you are having trouble dealing with voks stgs I recommend you post some replays here for tips. Upgraded riflemen, tommies, and guards will be winning against volks, you may be doing something wrong.
oh dont get me wrong, i have no problems with dealing with volks stg. i find it unfair for an okw player to have access to such powerful and cheap infantry on top of having a capable rooster.
i understand stg volks can be controlled with upgraded rifles and tommies, but all these dont come free, they require research, fuel and then munitions. guards are great units, but are 360 per pop and further 75munitions to be effective. but they are not as cost effective as volks and there are probably going to be more volks with vet by the time guards are on the field. bum rushing guards and abuse volks short range dps is going to beat guards hands down, no contest, while conscripts shoot uselessly at volks.
stg volks is just part of the major problem, whatever other armies can do, okw is can achieve, except often with better units, lesser micro and allowance for more errors.
this is just vcoh ranger/airborne spam all over again. sure there are counters, but it will be harder and far more taxing to counter.
