Matchmaking - Russia

So I’m trying to keep this positive, but I’m fed up with playing with russian teams.

When I grinded the Japanese Ground TT I got paired with Russia most of the time and now that I’'m grinding the American TT I end up with playing with Russia ~90% of the matches, often I’d find Russia on my and the enemy teams.

This is currently predominantly at 10.3, so I understand why there are many people playing Russia, but why does the Matchmaker throw Russia on both sides instead of having Russia on one side and the other nations on the other?

Why is Russia paired with the Americans most of the time?

I’m really sick and tired of having to deal with russian team mates…every now and then I’d love to win a game too.
