Every time i play SWAT i keep getting SWATNUMS!

Even though it’s purely meant to be random selection with game type rotation, i constantly get SWATNUMS when i play SWAT with a ratio of 5 games with magnum to 1 game with the BR, who else has had this problem? and who else thinks the DMR should be added to the rotation like it was in Halo 4?

Magnum > BR anyday and I would love to see them add the DMR too
