It takes 3 seconds at the end of a match to select someone for a commendation.

If your team just got massacred and you want to be as far away from those people as fast as possible then you're not likely to stop and toss out a commendation. But when you've just destroyed another team or someone pulls off a last minute turn around that wins the match? Take that incredibly small amount of time to thank someone for a job well done.

It's damn rude when you finish a match to disappear so quickly someone can't even say thanks let alone pass out commendations themselves before the room has emptied out.
