MCC Halo 4 Slayer Map Rotation

Good morning.
I played over 45 games of slayer in Halo 4 on MCC yesterday (we’ll sidestep the issue of why I played so many games in one day…but one issue was, it was raining all day). Over 45 games, and we NEVER saw Haven or the Pit ONCE! Are these maps gone from the rotation despite the rotation list?

Since, I’m here I’d like to make a request. Can we have less Solace and can Harvest return?

We would really just like to play Haven and the PIt some.

Thank you.
