Lack of Ranking system in custom group lobby discourages new players

The demo brought in new players.  But when they join custom groups (that doesn't say noobs), they get killed by the experience players and alot of them are getting discourange.  There should be a way for people to roughly tell the ranks of other players.  So new players will see they're playing against alot experienced players, and might play another game.  Experience players don't enjoy stomping new players because no challenge.  Better UI in custom lobby please.
