Everyone whos involved with BTS seems to be winging this event. TSC has always had some ego/social issues, so his stance on all this isn't surprising. It's really no shock this game is dying when yall being assholes to each other, holding grudges like you're in high school.
"You made a mistake 2 years ago? Good fucking luck because we won't ever forget or forgive what you've done. Playing on the same team as people we don't like? Your team has behavior issues and can't come to our b4nny party "
Fuck this way of thinking. I'll see you at RGB, the only tf2 event in NA that really matters.
