You are going to have to adapt to using micro and combined arms to kill tanks. 2-3 Volks will no longer be able to A-move and shoot a Pershing down to half health w/ good RNG.
You say "fausts don't help." Yes, yes they do. Even top Allied players drive their vehicles (from UC to heavies) into Faust range all the time. The OKW ATG may be crap compared to Pak-40, but it can freaking cloak. One Faust + 2 cloaked ATG (properly positioned) = dead Allied light / medium tank.
PIATs aren't reliable and Zooks lack the penetration and damage against high armored / high health Axis tanks. Soviets / UKF and lesser extent USF have always relied on proper use of combined arms (snare / ATG / infantry support) to kill Axis tanks. I don't know if you've played a lot of Allies but what you're struggling with as OKW is something Soviet has been doing since 2013.
Jesus Christ, I never said anywhere that I miss volks w/ A-move panzerschrecks. I just want something better than a raketen. Something that isn't one-shotted by any explosive weapon. The fact that it survives past 10 seconds in combat is 100% RNG dependent, and you can't even put distance between a tank and a raketen because it has an absolute shit range.
but it can freaking cloak.
Which is great for defensively supporting retreating squads. Notice the wording: "defensively supporting". It's meant to defensively support squads when pushed back, not to be the backbone of your early-mid game anti-tank capabilities. It not only greatly limits your chance to be offensive with infantry, but it also can barely be effective defensively w/o being wiped. Unless they're adding more squad members, or buffing the range, it's a waste of manpower. At least PIATs and zooks allow you to be offensive. Trying to be offensive with volks + raketen is like trying to carry a suitcase full of rocks up a 20 story building (without an elevator). The fact that schrecks aren't being re-implemented on a different unit single-handedly defeats the purpose of OKW's faction design of being offensive and keeping constant pressure on your enemies. It's slowly turning into Ostheer where you have to react to your enemy all the time, and almost never the other way around.
Also:
Fausts ARE useless if you have nothing useful to support it.
