Obviously you didn't watch the games. Both took turns playing each faction (Ost vs USF) and USF easily dominated in both games. If that's solely the result of the "bug fix" for grens then maybe USF is really op.
I did.
And guess what?
It always looks like this first week after the changes.
Guess what again?
BAR buff have no impact on bar RET play, because you don't want to get close with RETs unless you have to, you just need to have multiple of them around with the weapon equipped and that isn't exactly cheap.
Maybe, just maybe they shouldn't have build a sniper against allied version of osttruppen and went for 2nd HMG instead to actually control swarms of weak infantry?
USF changes affect purely Rifle gameplay, especially in late game when they get to vet3.
