Why does the game refuse to give me modes with bases when I need base kills??

There's no way I'm imagining this. Whenever I get a BP mission that requires I kill bases, suddenly I'll get like 10 matches in a row that are nothing but Domination or some other bullshit with no bases.

It's already hard enough to get them because losers in this game that can't win against other fighter players camp strikers/bombers, why the hell would you not let me queue up only for base killing modes if I wanted it? Or why wouldn't you make the matchmaker give me MORE of those maps, not less?
