The first major problem is the insane potency of light vehicles which force Axis off the map, making them invest in AT early on before Allies and potentially losing squads early on. The second major problem is clumping which results in cheesy wipes from tanks and from mortars. T-70/Quad Half Track/Stuart/AA Half track obviously just need a damage nerf. Easy.

Then the other issue is clumping, which I think can very easily fixed by setting a maximum models damaged per shot at 2 (like mines) for tanks and 3 for indirect fire (with exceptions) Tanks can have their scatter reduced to compensate, in order to give medium tanks more consistency which they currently lack. That's just a general quality of life consistency change which will benefit Wehrmacht the most. I'm working on a mod where I've done this,and it's working brilliantly. Double equipping Bars and Brens should also be removed in exchange for a vet 5 nerf to OKW infantry to keep all infantry scalings balanced.

Giving Ostheer 5 man squads is going to completely break the balance vs Conscripts which is already pretty lackluster, and it'll still leave OStheer vulnerable to cheesy clump wipes.

"T2
-Boster Squad
increases squad size of Assualt Grenadiers, Grenadiers, Panzer Grenadiers, Pioneers, Osttruppen, and Stormtroopers by 1"

Good lordy 5 man Panzer Grenadier squads is going to be OP. Panzer Grens don't need a 5th man.

Obers are 400 mp, I really dont see how people can use such an expensive squad for tank hunting/ AT gun screening.

That's exactly another problem. 400mp is far too much. 360mp would be reasonable since they have better received accuracy bonuses than PGren's.

This is how I have changed Obersoldaten in my mod that I've been working on.

"Obersoldaten
Moved from Panzer Headquarters to Battlegroup HQ
Can be equipped with double Panzer Shreks for 120 Munitions. Incompatible with other upgrades
Manpower cost decreased from 400mp to 360.
Kar98k Rifle accuracy reduced by 10%
Reinforcement time reduced from 12.5 to 9.5
MG34 upgrade replaced with Infrared STG’s. Requires Panzer Headquarters
IR STG’s now cost 90munitions
Received accuracy nerfed from 0.7 to 0.8
This is to balance out the squads price reduction and fact they come earlier
IR STG’s cover ignore bonus removed

To get back to your post: Are you sure the rate of fire ist the same on the Ost and USF mortar? I know the Ost one is pretty fast too, but I got the feeling that the USF one is even faster. Might also be some bias from my side.

As far as I can tell looking at the stats, the rate of fire is exactly the same even with veterancy. It just gets 20% less scatter at vet 1 instead of the counter barrage, which is obviously a beneficial trade off.
