I really like the Ranked points, basically all I had in mind. But I wonder, is unranked really necessary? I can't see people feel a use for it, especially with how easy it is to make a lobby.
Unranked is good for low-qi players that want to use it I guess.

Edit: Just like Kratos said below me, yes. Black belt restriction please. There's a huge gap in skill between brown and black. OR, if possible, match people with relevant qi.
