OKW had a ridiculous amount of AT potential, I fail to see how removing them from shreks would "fuck" them at all.
Soviets don't have "Hard AT infantry". And a lot worse options than OKW in the destroyer department. And OKW have the cheapest, earliest, AT gun in the game.
yes they have AT potential, but potential doesnt matter when you cant reach it because you get boned so hard in the early game by light vehicles. players would lose pretty much all skirmishes on the sides of the map in the earlyish mid game because they dont have AT support nearby, and they would have to spend a rather large amount of manpower on units that only excel at AT and not much else. basically you have no mobile counter to light vehicles other than the puma.
