I would love the option to specify certain settings before entering a game, like "minimum kill cool down", "player speed", "discuss time", etc. (at the moment we can only specify server and language).
but just generally things that won't have to make leave right away after joining a game.
(I really dislike playing a fast game where there are 4 kills in one minute, and at discussion time everybody just yells out colours instead of discussing things).
I really just like it more as a strategy game than an action game.
