A Random Third Voting Option?

Over the past couple weeks I’ve noticed one thing about Halo 4 that really is making the game repetitive for me. The Maps. Every playlist I go into its always the same maps being voted again and again and again. Perhaps instead of showing 3 choices be shown, have only 2 be shown and a third blank random option which would help a gamble and randomly choose a map to be played. This would possibly cut down on the times Ragnarok and Haven are constantly played. What do you think?
