Disable Team Builder Group Disband When A Player Leaves.

If a player leaves a team builder group while your team is searching for a game, then your group will disband. This makes no sense to me and is kind of lame. Why do the other 4 players have to wait and find a new team when someone leaves the group? The group should just be removed from the match making queue and search for a new player instead of disbanding. I play team builder a lot and this happens quite often.
