That's actually not true - OKW's schreck is a different weapon (game files wise) than Ostheer's, so nothing stops Relic to change one and not the other.
And why would shrecks need a nerf!? What is OKW suppose to use as their standard AT if they do get a nerf? The Rankenlol? The single tank that they can field all game? While both russians and USF bring 3+ tanks to the game. Good plan bro.........
