Some of the things you've just asserted are hilariously untrue though.
Ostheer has no elite infantry? What about Pgrens?
only Sovs/USF can pull light vehicle timing pushes? What about the Kubel? Or more seriously, Puma or Flakhalftrack.
Only one side has useful artillery? What about the Stuka zu Fuss?
Indeed, half of what you've said there is at the root of many faction's balance issues (OKW truck pushing, Why do we need it? It's the height of unrealistic stupidity)
Pgrens are not "elite" conceptually nor factually in game. Obers, Shocks, Paras are elite infantry that can operate independently and defeat every regular inf reliably 1 on 1. Pgrens, at the best of times, are what covers your flank on Semois/Stalingrad.
Kübel is an occassionaly annoying suppression platform that gets hardcountered by....the M3. Or the Dodge. And is usually dead by minute 5. Ever seen a Kübel wipe squads, decide a game, etc?
Puma, Flakhalftrack? Ok, you might make that work. Even though they are both actually more defensive/reactive units.
I see a Stuka in 2s occasionally, usually as a reaction to heavy Soviet t2 play. Problem is that it will delay your Panther too much to be generally viable, but hey, in an AT, your partner might compensate. In 1s, its a very, very rare bird that you cannot afford unless you are hilariously in the lead already. The unit itself is strong, no argument at all, but it has at best a niche in the current meta, so while you have a point there, it frankly was not even on my radar since I dont see it often.
