[In-game timer?]

How can I see the time since the start of a game? While spectating or watching replay I can use summary.. but can't do that while playing. Having one is important for strategy games. Good for improving your economy(comparing economy with older games), for timed attacks and so on.

[Host exits from Rated 1v1 game]

So if the host just press exit or ALT+F4 the game, even though is rated, there is no winner. The guest just gets the message -> Host has left the game and the game is over. No change in rating..
