Server Regions not working

I set my server region to USA, but out of 5 that I played, I got 1 USA region game. The others were based in Europe and Russia. Is this supposed to happen? This consequently makes me lag, which makes me unable to hit or fly any interceptor. My toaster usually gets at least 20 fps. In these games I got maybe 5 fps. Please help/fix this/clarify. 

It works as prefered region, if there are not enough players from the region to create a battle, it will select another server.
