Currently when you queue for CC (or any PVP mode) you receive virtually no information about the state of the queue. How many people within your bracket are also queued? Are there games in progress? How many? How close are these games to finishing?
Ideally ALL of this information should be displayed.
Another way you can find at least parts of it would be to allow you to spectate games in progress. I don't care so much about the ability to spectate as I do about being able to click a button and receive an error message along the lines of "No match found", instead of waiting in queue for 30 minutes just so I can be sure that there isn't only a single match that's going deep into overtime.
