Not sure when they added more maps and more game types, but havn’t played this game in months. I have been playing other games like overwatch and Halo: MCC. When I came on halo 5 again two weeks ago i noticed Community Action Sack and more maps in BTB 
I am so excited and has renewed my love for Halo 5 and has given it another chance. I really hope they keep adding more community versed playlists.
I would love to see a Community Social Slayer gametype! There are a ton of fantastic community maps going around, it would be a shame to not see them in matchmaking.
Yea it’d be fun as a monthly thing. Help inspire people within the community.
I’d love to see some community maps in Slayer! The ones they added to Halo 4 matchmaking were amazing.
