Future Playlists

What future playlists would the community like to see? We have a good selection, but there is not enough. Existing or an idea are both acceptable. I personally would like a action sack or something similar. Stuff with rockets, shotty snipers, etc. I would also like a true FFA while the main objective is to kill. The only problem is that while choosing what you will play, you only pick a map. They need to update it to where you have a choice between this this and that, only in playlists that feature multiple game-types. What are your thoughts?

Some team doubles. Action sack like you said and maybe multi team.
