They really should have put a system in so RQers lose 75-100lp while the winner gets 50lp imo.
The thing is that, especially with the fact that the server can screw itself up sometimes, this would punish players who have genuine disconnections for no reason. Something like it could be implemented without punishing the disconnecting player, though, like awarding the opponent their points, but there still needs to be a punishment put in place for serial rage quitters (observed by high disconnect rates).
The solution needs to take into account possibilities of an actual network issue, and that's what this is doing in theory. But I'm getting bad vibes from it, because this might not be all that effective. The timeout period needs to be elaborated upon. The amount of disconnects to get to that state needs to be elaborated upon.
