It would be awesome if in ranked multiplayer, we could have the option to select specific settings for the 7 maps that are selected from a pool.
These settings could include a random modifier where players are required to play with a random civilization, a 9 villager modifier to speed up the game on closed maps, or a restricted pool modifier where players are only allowed to choose from a subset of civilizations.
However, players who are not comfortable with these modifiers can still ban the maps that have them.
