1. Unranked mode
An unranked mode, that works exactly like normal mode just without elo. So that you have turn times and the opportunity to kick people if they do not play.
2. Different elo for different game modes
I suggest this mainly due to the difference of real-time and turn-based games. Those two modes are absolutely not comparable and having just one elo system combining those two game types does not make a lot of sense.
3. Punishing players hard for leaving on purpose
As it is right now, everyone can just quit a game if they get tilted and jump right into the next one without any immediate consequences. To differentiate between the players leaving on purpose and those with blameless behaviour there should be a poll after each game with a leaving player, asking the other players if they think the quitting happend on purpose. The results should be used to immediately punish the player with a ban depending on the outcome.
