Assymetrical balance. Ostheer needs a weakness and to compensate, it has other strenghts. You can´t run around and demand everything for the faction. They already have great support weapons. But those alone don´t hold the faction up. So it´s either Grens or the lategame. And imo lategame buffs make more sense to not have the same faction x5. There is enough infantry spam already.
We dont get compensation..that is the problem.Wehrmacht armour is not definitively superior at all asmuch as allied indirect fire and infantry are compared to german.Tiger has become redundant.same for panther.Pz 4 overpriced.Stug is the crutch unit for armour that keeps faction alive,same way sniper is for infantry.
As ostheer HAS many weaknesses...amongst them the abysymal repair situation and squadwiping potential due to low member count,no cost effective armour except stug,very difficult time properly countering blobs,no real light vehicle play,no real early counter to emplacements etc etc.
