I think that there should be a feature that allows brackets in tourney servers and being able to play more than one game at a time. It would just make the tourneys go faster allowing more tourneys to be played. Spectators could choose which game to spectate and could spectate multiple games at once.

That's good idea. It's boring to wait when you have like 14 players and you're the last.

Just be patient and wait,you can observe your opponent while you wait and learn to counter it,this would fail if one person suddenly leaves from one of the matches.

This: is an excuse to multi-clienting.
