any way i can get it down?
Play auto-1v1-games. I know it's manageable with multi-day games. Not sure how quick you can do it with RT. Probably faster, but not 100% sure.
Hey, if you're really desperate, just join a bunch of 'surrenders happen immediately' games, and surrender them, immediately. You don't have to win any games to get your boot rate down. Of course, your win rate will suffer, but that's much less important.
