Add all Halo CE maps to playlist

The matchmaking in this game is unreal. How about adding all the maps from CE to the playlist to maybe get more variety. Choose from 3 selections and 90% of the time 2 are the same map. Can we get a TS and CTF playlist for CE? All I see is players choosing TS and CTF. No one is choosing Oddball or KOTH
Also games are not ending when the other team quits out on CE
