An update to the Team Fortress 2 blog discusses the admittedly rough launch of casual mode in Team Fortress 2, Valve's multiplayer shooter. They offer a new patch to address some issues and remove leaver penalties, and say another patch will follow to allow players to specify the maps to join. Here's a rundown on their concerns:

First, and most important, queue times. The queue times you are currently experiencing are a bug, not a feature. It is something we are actively working to correct. Several backend issues appeared post-launch that culminated in long wait times. Removing this issue is our highest priority right now.

Second, abandonment penalties. We had put in a ten-minute cooldown period to encourage players to complete matches. Your feedback has convinced us that it is more important for players to be able to come and go as they please. Today's patch will remove abandonment cooldown penalties from Casual Mode.

Third, user choice. We'd intended to roll out the number of match options available to players incrementally, so as not to overload the matchmaking system with too many variables on Day One. In retrospect, of all the match options to hold back, map selection should not have been one of them. It is the next feature we are adding to Casual Mode, and you will get it very soon.

Fourth, Casual Mode levels. Levels are a cosmetic feature that show how much you've played. They can never be lost, and they do not affect matchmaking. We did a poor job of communicating that Casual Mode Levels are in no way similar to Competitive Mode Ranks (which do affect matchmaking, and can be lost).
