Maps and BR

Can anyone tell me why in BR 1 Soviets there’s a constant default to playing Japan. I actually look foreward to play Moscow or Stalingrad but if I do happen to play the Germans its Berlin.
Its a good way to kill this game IMO, playing the same maps over and over dispite the game mode.
BTW I’ve down ticket the Manchuria map but it I still get it over Moscow maps in all BRs

If you’re a beginner, I suggest you practice upgrading your weapon and squad attributes first before challenging higher-level rooms, rather than rushing to choose a map. Different maps require different tactics and combat styles; blindly choosing a map will only hinder your teammates and won’t help your advancement.
