I remember one issue I had with the lobby was that it had 100 people capped, and there were multiple lobby chats.
That, and players who were red were in-game and can't read the chat, people who were yellow were AFK, and green were few and far between.
Perhaps remove players who are in-game from a lobby? Or sort based on color and then name? It just seemed kinda weird for the lobby to be sorted in such an odd fashion that made it hard to PUG FTs or meet new people.
