I think those statistics are a bit flawed because they include all matches, rather than the top-200 only. Why do I say that? Because there is no question that Axis are far easier to play at a lower skill level.
If you include all games, the win ratios for 2v2 look like this:
UKF: 41.5 %
Soviet: 46.0 %
USF: 45.3 %
Wehrmacht: 55.3 %
OKW: 55.2 %
Once you look at the Top 200 win rates, things change because people have an understanding of how the game works.
UKF: 48.2 %
Soviets: 53.4 %
USF: 47.4 %
Wehrmacht: 50 %
OKW: 49.4 %
That's a drastic shift in percentages. Why? Because people have an understanding of how the game works. Take the MG42. At the lower levels, most people would argue its the most oppressive unit in the game. At higher levels, people know how to counter it, and most people think the Dshk or the .50 cal is the far superior MG.
Now, having said that I do believe Axis are currently better than Allies, but I would caution about using statistics that include players who have little to no understanding of how the game works, which makes any argument about balance difficult.
