I changed it once. But cool. (Also, a little weird coming from someone who’s just done the exact same thing. Guess you use it to discredit yourself too…)
Still, leaver system works fine. You still only lose 25. And then game is still winnable 5v6.
Or you can just wait and leave too and reque.
You aren’t really being “punished” if there is a leaver either way. You either stay and have a harder match, or leave and get a new one quicker. And if losing 25sr is going to upset you that much… maybe ranked isn’t the best place for you.
Personally I just wait till the time elapses and then just leave too.
