I got to Gold this season but after going on a losing streak and winning a couple of games in between I got demoted to Silver I. I was just wondering what happened to the notification you were supposed to get when you were on the brink of being demoted. I'm not salty because I know if I just refocus and stop tilting I can get back into Gold but I'm just curious about the notification before you get demoted. I also heard your MMR had to be at Silver V in order to get demoted to Silver I.
