OSF:
I think Rifles in general need slight adjustment, more so the commander giving vet rifles for the same price. Should probably just put it back to being a unit you build from tier 1 with increased build time. Maybe push it to 1CP? The LMG's need some sort of change as well, though I'm not sure how.
M15, maybe just swap it with the AT gun and put it in T2. Extra fuel for the captain should help delay it a bit, not to mention your AI power is reduced by having no LT.
Jackson and needs its target priority fixed.
OKW:
I think Volks could use a bit of a buff, maybe give them a slight boost without any vet, but don't gain quite as much when they do vet up. Helps with the early game but mid and late game remain unchanged. Imo they are more useful mid and late game compared to conscripts because of shrecks but salvage is also pretty useful.
I think that Obers, Panzerfusiliers and maybe Falls should receive some nerfs with their Vet 5. They just become monsters when they get that. It's not uncommon for me to have a Panzerfusilier squad with 100+ kills at the end of a long game. Early on they can struggle vs rifles (officer helps a lot tho) but there comes a point where they just stomp all over everything, because they do so much damage with G43's.
Kubel doesnt need changing imo, except for the awful pathing but this is something that is an issue with many vehicles in the game.
Jagdpanzer is fine to be honest. When micro'd well it does really nice damage and becomes pretty hard to kill. I much prefer it to the SU-85 by a long way. Had a monster game with one the other day

Economy wise, I don't have an issue with it. Sure they have reduced resources but they have very strong infantry excluding Volks (which are still ok lategame with shrecks). Being able to swap between Muni and fuel I find very useful. I love salvage, some extra fuel as well as denying your enemy support weapons.
I think the Stuka HT needs to have its rockets behave like the Panzerwerfer, so instead of a straight line it is more scattered. Maybe unlock creeping barrage at a vet level.
Sturmpios should stay the same. Yes they are pretty powerful and do very nice damage at all ranges, but its a big loss if they die early on. Loss of firepower (that volks can't really make up for) and the loss of a repair unit as well as being expensive to replace.
I think the Sturmtiger needs adjusting. I never build one because of how unreliable it can be. Having it explode against fences instead of vs the target sucks big time and for me makes it a waste of resources and pop cap.
Soviets:
I think conscripts and penals need to be separate more in their roles, as they are too close right now. I would like to see Ppsh become a core ability to unlock / research to help conscripts scale into the late game. Ppsh has become a fair bit more useful since it was buffed slightly.
I think SU76 should be swapped with T70. T3 gains some long range light - medium AT. I think the SU-76 could use a small penetration buff though, as its all but useless against heavy armour. T70 in T4 would give some AI capability as well as providing a scout for the SU-85. Should make teching instead of relying on call ins a bit more attractive.
I also wonder whether T-34/85 should be removed as a commander ability and instead some form of upgrade, to once again encourage the use of T3 instead of just call in spam.
Maxims is a tricky one. They probably need slight adjustment but I can't help but feel that maxim spam only exists vs OKW because of how weak their core infantry are vs OKW. I dunno, but any change needs to be carefully thought out.
Wehrmacht:
I've barely played them since WFA release so cannot really comment
For what its worth, I've played most of my post WFA games as OKW.
