I literally had an unpredictable power surge. (Nice weather and no unusual use of power in the house) I instantly regained power and proceeded to log back into overwatch. My game was still in progress. We won and I received a heavy penalty to my SR and a timeout to join comp games. THIS IS RIDICULOUS. I have never intentionally left a comp game. My computer is of very high specs so I was not even gone for more than 5 minutes. I want this corrected. This is completely unfair.
Unfortunately, they have no way of telling if players are unplugging their modem/computer to avoid a game, a loss, or any other reason. SR is never awarded back, under any circumstances. You can read more about this policy, and why it exists, here: Overwatch Technical Issues, SR Loss, and Leaver Penalties
