I don't know if it would be simple, since the scoreboard already takes up a majority of the screen, to add in chat after the end of the game.

The citadel often gets destroyed in a few seconds leaving little time to say gg, or actually discuss the game you just played.

You could have a post game "lobby" or something, where you can chat and work out if you want to play another game or something.

seconded. End-game is often where the majority of discussion takes place between teams, especially constructive discussion such as "how do I deal with strategy X", etc. Sure, it would create another opportunity to flame, etc., but I think it would bring a lot more good than bad.

a post game lobby would be nice, with acess to detailed statistics missing from actual scoreboard..

yeah it's weird how everything sort of freezes, like "STOP, hammer time."

From what i understand, the chat systems have not been fully implemented, and this is one of the intended features. I could definitely be wrong, pulling from memory something that was mentioned in passing.
