First off, I feel we desperatley need more game modes like infected and a normal private lobby hosting system, instead of a dumb vote system, and match settings to be decided within the lobby instead of map.

As for custom settings however, I personally feel we need a lot more match settings for multiplayer. I remember Call of Duty having a good set of options for private matches. I.E number of respawns, player health options, a chosen number of custom loadouts given randomly to one player (be good for a mike myers game mode), seperate voice channel for dead players and alive, and one that I haven't seen anyone asked for before, an option to hide the kill feed.

The reason I ask for this is because I enjoy playing and making maps for Mike Myers so that me and friends can have some fun and laughs. However with a simple option of no kill feed along with the other options listed above, we could create a game mode like the popular Murder game mode from gmod.

Not only would these options help me create a game mode like that, but I am certain that the community will come up with more custom game mode ideas that you wouldn't usually think of.
