I have to agree with @Ghosthree3 because honestly, I don’t think I’ve used quick-match for a long time now, and I would never dream of doing so again. Server browser is the best way to join a server, and as he/she said - the real question is, why even have a quick join button?
OK, so I mean that slightly jokingly, because of course there are likely some more casual or drop-in-drop-out players out there who appreciate the button, and it’s a fine feature to have, but I’m fairly certain almost everyone level 10+ uses the server browser anyway. If you are level 10+ and want to play on a level 10+ server and there aren’t any, just join an empty one. Most of the time I play (unless it’s early morning EU time - the quietest time) the server gets at least 4 people on each time quite fast and will fill up soon enough. ^.^
