I think OKW having the faust reverted was perfect for this reason. It highlights the terrible design flaws of OKW (that still exist to this day), and will hopefully mean the balance mod guys can be drastic with OKW like giving them a pak40 or something.
But it's not perfect for OKW leaving them with dead Mech truck and microing their asses to counter Clown Car which means huge disproportions in micro.
Not to mention that pzfaust affects only M3 for Soviets, so it doesn't affect any other strat than M3.
Becasue of this we are facing tunel vision.
Knowing that there is early pzfaust you must consider if you want to micro M3 or maybe go for Penals of Cons spam or Maxim.
Knowing that there isn't anything to stop your M3, you will always go for T1 and Clown Car.
This way you just kill plenty of strats for the one most powerful. On the other hand with early pzfaust you have few similar strats without any being too powerful.
