Matchmaking map rotation

I play H3 and Halo Reach matchmaking, and it is frustrating to play some of the same maps over and over again.
I keep seeing countdown, reflection, pinnacle, and uncaged (along with some others) in the team slayer playlist.
With H3, I keep seeing Boundless (a great map, I think), Pit Stop, High Ground, Construct, and Guardian (I like this map as well) in the team slayer list. It gets really old, and in Halo 3 i’m sick of hearing the same death scream over and over. And the elite death scream sounds horrendous.
Anybody else bothered by this?
