-Queue time was amazingly fast. That plus the fact they needed to increase server capacity bodes well for matchmaking.
-Rollouts feel awkward with the closed door and walking around and the round-start fullscreen thing. Would feel less weird if the door time was the same between rounds... I actually think the longer time is better in case you get a shit spawn (like right side on Granary), but really freezetime + explosive jumps feel more controllable since you don't get everyone clustering at the door holding W.
-Friend hosting a party at one point got put in an empty server alone immediately after clicking the queue button, while the rest of us got an error along the lines of "the game has ended," and all of us remained in the party screen with the host still listed. Host came straight back to party screen himself after leaving server.
-Should have DPM instead of flat damage, as it's more meaningful. Total time played would be another good stat to have alongside it. Probably deaths as well, even if only visible to yourself (I'm assuming Valve doesn't like the idea of displaying that to everyone since they never have), so people can use it to help themselves improve.
