Last but not least those Jäger barely manage to defeat the Tommies. Looks fine to me.
As others said already and differed from op by doing so (including me) it is not the 1vs1 combat situation that is broken but multiple squads versus multiple squads. OKW and USF clearly profit the most at the moment because their infantry squads perform better when amassed and are more of an allround solution to combat multiple different threats. This wasn't easy to counter before the patch but it got worse now. So Wher, SU and UKF struggle in infantry combat of bigger scale versus WFA factions.
