Matchmaking disaster with player from different continents

Especially at night after European time, playing is a disaster.
Then players with e.g. typical Chinese names come into the game and it lags so much that it is almost only a slide show.
As soon as such a player leaves the current round, it runs smoothly again.
Are there no servers where only Europeans (or Americans, or Asians, etc.) play?
I will leave such rounds in the future instant and look for something new, because the game is so no fun.
