New multiplayer modes?

when are the fun playlists coming. Like infection or BTB. Kind of in the bored zone with this game. I usually have a fun playlist to dive into but nope only 5 ranked playlists and doing the 10 to qualify is a chore and warzone is decent but I feel something is missing in that game mode.

Team bases, x amount of vehicles and power weapons that is fun halo and should be standard playlist at release.
