Is this a balanced gameplay really?

How are the statistics behind these results?
Country USA
BR 10.3

Simply want to develop USA tree because I have mainly a collector gameplay.
If I could have a different gameplay behavior or motivation (KD ratio example), will simply select another country (Russia perhaps?)

The unfair unbalance is an statistical fact.

Please developers… could you improve this problem?

The combination of this BR with the craziest players and event time isn’t the best…

I fly Ayit for event. Doesn’t matter which nation I fly with, it’s always a magnificent spectacle, plaque vs cholera.
