I also like how people can't suddenly pm you at any time, including after the game. Sometimes people were abusive and the box would suddenly pop up in your face without warning, making it hard to avoid. I'm not saying private chat shouldn't be brought back, but perhaps limit it to those on your friend list in future (assuming that's fixed properly first). I guess there is private chat in a way, as you can carry on the convo with your opponent even after the game has ended which is neat.
