If stats were available since launch and included all pplayers ( not just top 200). I guarantee the OKW winrate is probably around 90-95% in 3v3 and 4v4, 80-90 in 2v2, and 70-80 in 1v1. While both allied faction winrate would decrease atleast 20% for every game mode.
Well I would of course believe everything you guarantee, Queen. For your only target it's the perfect balance. Seen from allied perspective, of course.
