Anybody think Relic is going to respond?
They won't do that. As a company you never admit that you are wrong or you'll just add fuel to the fire. But they did write this in the changelog of the last hotfix:
OKW Economy
The previous increase in munition rate for the OKW significantly increased their potency within 3v3 and 4v4 environments to a point where it became problematic. This compounded a number of issues which resulted in the faction significantly over performing relative to its counter parts. Until we are better able to identify and resolve those compounding factors, we are going to revert the munition change to a lower value.

They indirectly admit that OKW is overperforming in comparison to the other three factions. OKW is becoming even stronger with Ostheer support (bunkers, MGs, fuel caches) which in return yields a high win rate for the Ostheer players as well. Coordinated Allied teams don't suffer from this as much but I understand why the sheer amount of super heavy tanks and vet 5 infantry becomes uncontrollable for any set up of random USF/SU teams.
