I think it would be really nice to have the option of selecting a minimum rank for players to join a game you create. So for instance, if I'm a beginner I could choose that only those beginner and above can join my game. Or, as an intermediate I could say you need to be a beginner ... or if I wanted a really good game against matched opponents, I might require intermediate and above. A lot of times I'll join a game and the host is kicking people. That's fine, it's their game, just be nice if that was an option when creating the game so everyone knows what is going on and is patient.
