First off, this is not a rant thread, I would really like to hear a discussion on this unit from high level players (my OKW rank is fairly low, so feel free to take that into consideration when telling me why I'm wrong!).
At the moment, it seems Volks are just in control of this game, either when I use them or when they are against me. They are cheap and spammable, as is their flame nade, which can shift pretty much any engagement in their favour - it basically denies cover and garrison use to the other team. Their StG upgrade is cheap and effective, and the on-the-field timing means that upgraded Volks often face unupgraded enemies, and can easily push more expensive units off the field in many situations (Rifles, Tommies, and sometimes even Penals, depending on the map). Their faust does not require either vet or side-teching, and so once a few Volks are on the field, OKW has fausts everywhere.
This isn't exactly correct. I play lots of OKW and have ever since release. It is true that their current stupid position sees them make Panzer Fuz and Obers almost entirely fun rather than required.
First; vet 0 non STG Volk are awful and need to fight at long range and in cover to even remotely do anything. They get owned by Tommy in cover, Riffle at med range and Penal. For Volk to be of any use they have to be heavily invested in with both their upgrades and vet. If you lose your highly vetted Volk mid or late game you will never really recover from it.
Second; Faust is NOT available with out tech, you need to deploy a truck. In fact I would argue that I am nearly forced to get a Med HQ/Mech HQ ASAP because of the prevalence of Clown cars and other stupid early light vehicles. Raketon is an option but their horrible accuracy and poor mobility early makes them a second choice.
Third; whom ever is complains about flame grenades can go jump off a cliff, because at this stage of the balance cycle it is literally the only viable weapon against garrisons for OKW early to mid game. Field guns are still bugged and some times can't shoot buildings and other flame weapons are locked behind a subjectively sub-par doctrine.
Fighting against Volk is just a case of supporting your units correctly, and not sending good after bad. If you see the STG upgrades and you do not have any Bren/BAR, do not fight head on if you can. You should never fight battles you clearly wont win (unless you can get cover advantage or what ever).
