I logged in today to play some ranked after the new penalty was added in. I hadn't played since I completed my 15 games and was waiting for the penalty to be added. I just logged on this morning and as soon as I went on to the war map my rank showed up (Diamond 3) and it just went down 70% to Diamond 2 for no reason. I have a video to prove it in case it needs to be shown. Is this just decay or was it a bug?
Here is the video:
Also sorry I got the values wrong it was about 35%, it's just that I lost 70% shortly after in a duel so I got it a bit mixed up.
