On your service record for MCC, the Kill Death and Win Loss ratios are both including custom games.
Yea, that need to change and have Customs separate from MM. Destroying my K/D ratio just because i want to use Custom games to practice against better players is wrong.

And my service record is only showing 1 of the 5 custom games played
If you look at campaign progress for MCC in your service record there is one slip up. When you select Halo 2 and Co-op play the mission the armory is listed as incomplete and it affects the completion percentage. The Armory is a mission that can ONLY be played in solo campaign therefore it will always be an incomplete unless its changed to not show “The Armory” when Halo 2 and Co-Op is selected.
