So are the USF players who have far more wins than OKW players in 1v1 going to have their ELO adjusted now?
I didn't see anywhere relic saying that USF was ever OP.
However you have quotes in this as well as previous patch notes confirming that axis and OKW are much easier to play/OP in comparison to allies so, thats your answer.
Rewording for personalized version:
Just because you're bad doesn't mean opponents army is op, however that is the kind of perception you can have as it originates from the lack of your own, personal skill.
@thread
I suspect this patch is the closest one so far to what we had right before WFA release.
Lets hope another one will address more underused units.
