- If UKF have a lower winrate than say Soviets, it might not be that UKF is a weaker faction. It might so happen to be that there is a disproprotionate amount of players or new players playing one faction over the other.
- If either Allies or Axis has the lower winrate in general, it is not neccessarily true that one is better than the other, it may be that one side is more popular than the other and matchmaking pairs unequal players against each other
- And especially this: just because "Mechanized is the 9th picked USF commander" does not mean mechanized is the worst commander. It means that it is the least picked, or it is the least popular. And people can not choose a commander for a variety of reasons from what is cooler, rarity, cost, and so on.
So I think it is a red flag when people use these stats to prove some argument (especially balance arguments).
Practical example: Axis has higher winrate than Allies on 4v4 but Inka Tournament showed Allies dominating axis. Why? Could it because Allies only gets good at super high level play? Who knows.
