I believe the following Ostheer changes would solve several major balance issues and improve the meta-game for all factions.
Wehrmacht Sniper moved to T2 - This change will prevent the Wehrmacht Sniper from inflicting massive manpower bleed on thre American and British players in the early-game.
PaK40 moved to T1 - This change will help the Wehrmacht counter the powerful Allied light vehicle mid-game. It will also allow the faction to skip T2, which is virtually impossible to do right now due to the dominance of Allied light vehicles like the Stuart and T70.
Panzerfausts require Battle Phase 1 rather than T1 - With the PaK40 moved to T1, the Wehrmacht will no longer require immediate access to Panzerfausts in order to hold off Allied vehicles like the Universal Carrier and the M3 Scout Car.
Wehrmacht Sniper cloak nerf reverted - With the Wehrmacht Sniper moved to T2, he no longer needs the super-long recloak time.
Moderate T3 building fuel cost increase - With the PaK40 moved to T1, many Wehrmacht players will choose to tech from T1 straight to T3 and rush armour. This change will make that strategy riskier and prevent Wehrmacht tanks from hitting the field too quickly.
A lot of these changes are unnecessary and most of the issues you raise are l2p (no offense).
1. Sov m3 are not a huge issue, but will be if you think pak is a better counter than fausts. m3 will just drive behind pak and wipe it. Same applies to Universal Carrier. No faust means Ost will have to keep all squads together or else get wiped by anything on wheels.
2. If you cannot get a pak out before a t70 or Stuart your either getting outplayed , not preparing for it or just need to l2p.
3. I don't see sniper to be a huge issue early game vs usf and its only recently been nerfed so I think more time is needed to test those changes. Ukf is a different story, but fix brits, don't go changing other faction as there are always flow on effects. I would suggest changing the capping speed of the sniper.
4. As others have suggested, minor adjustments. Personally I would adjust the time to Tech and build buildings and maybe reduce pak build times.
Finally, I wish people would stop trying to change each faction so that they all have access to the same units at the same time. I mean its getting quite boring as it is with Sov having access to maxim and morters straight away, and brits opening with mgs, and some others want usf to have access to mg and morters to start with. The more units you give every faction access to at the begging not only makes every faction almost identical but a nightmare to balance.
