I think it would be usefull to add some new options i general multiplayer lobby, allowing to organise available matches according to map star difficulty, bpm, ar, rank of players currently in match and so on. Every time i go to play some multi i have a problem to find a room with appriopriate difficulty level, and from what i have heared there are more people with this issue. If it was already requested then sorry, but i couldn't find anything.
