That's only for one month though.
For march, the numbers for Top 200 2v2 are UKF 40.3 Soviets 49.2 USF 48.7
For april, UKF 41.9 Soviets 50 USF 49.
Yes, but as the most recent one its the most relevant. For March, I would almost completely ignore the data because that is when the data started being recorded, so there are a number of variables we can't really account for, be that small data size or technical issues.
And even in the April numbers you can see the trend that's confirmed in the May ones.
Well Top 200 4v4 is even worse for example:
For May: UKF 36.6 Soviets 43 USF 40.8
April: UKF 45.2 Soviets 38.5 USF 43
March: UKF 43.9 Soviets 45.6 USF 48.8
The Top 200 WR% are not that meaningful though because the sample size is very small.
You have to go with the Top 200 though, especially in 3v3 and 4v4 because the average player in those game modes is significantly worse quality than in 2v2 or 1v1. In other words, the issue there is not always balance, but the fact that a lot of players outside the top 200 especially in 3v3 and 4v4 are just braindead and don't understand game mechanics.
Case in point, look at the most recent 1v1 statistics. All matches, the stats look like this:
UKF: 52.9 %
Soviet: 51.1 %
USF: 51.6 %
Wehrmacht: 49.9 %
OKW: 46.8 %
You don't need me to tell you those are nonsense. In no world are Brits the best 1v1 faction right now. In fact, the without a doubt best 1v1 faction, Wehrmacht, sits at a pitiful 49.9 percent.
Now, let's only check top 200.
UKF: 47.4 %
Soviet: 53.4 %
USF: 49.5 %
Wehrmacht: 50.7 %
OKW: 46.8 %
Looks far more accurate, doesn't it?
