if you lost more than 150 SR in a day, then you shouldve called it there. I have NEVER lost 500 SR ever. Well I did back in season 14… I was 1 tricking Genji and did NOT switch not to mention the last time I played was season 10 or 9. I went from a 2500 placement to 1789, but I climbed back up to 2307 after about 300 games lol
