I think the Brits adequately showed what happens when you'd remove snares from a faction. Replacing the Rakettenwerfer isn't an option either, as it would either leave OKW without an ATG (if you'd keep the AT/AI ISG in Battlegroup) in the most viable meta (Mechanized) or it would make Battlegroup even less attractive (if you'd move the ISG to the HQ).
I'd also be against units that efficiently serve two distinct roles at the same time. I never liked how with the ZiS going for heavy anti-tank also gives good AI (or anti support weapons) and by now it's clear that giving the M-42 a dual role was a mistake as well. The game is about strategic unit choices with limited resources and dual purpose units are bad for balance.
OKW does need some redesigns, but mostly to spread out the faction's power level more evenly across all stages of the match (tone down opening power, earlier Obers, etc.) and to get rid of some cheesy mechanics of certain units (Raketten stealth creep, Uhu, etc.) so the faction becomes more enjoyable both to play with as well as against.

I think he meant replace faust with at rifle nade that pfusies have tho so that might be a moot point.
I don't know that obers need to come earlier though. They already absolutely shred almost all allied infantry barring maybe rangers and shocks at vet0, and then only get better from there. If you want earlier elite infantry there's always falls too, who come plenty early and are still great (and can camo and have fausts).
