I don't know how you have disconnects registered by the server, but if possible, it would be great to add a message that informs you that your opponent has disconnected rather than quit. I’ve had people think I ragequit a match, something I’ve never done. If the server can’t tell the difference (I think j-wiz posted that was the case when the servers go down for maintenance), then how about the reverse – when someone hits the resign button in the menu, it would add a line informing the winner that it was a resignation on the rating change victory screen. Then, if that message is missing, you know it was a disconnect (or they closed their browser, but at least it’s more information than there is now).
I'd totally be down for more notifications of stuff like this. Consider: bug reporting. The person still in the game has access to a log that says "so-and-so disconnected at this time" and what was happening nearby. Imagine a world where playing Obliterating Hack against an Elf opponent with three attachments in multiplayer disconnected you: only your opponent would have the log.
