My Game Crashes just before comp starts and I get Banned… Fair? Never had ban in comp before… I hope Beta bug?? I was able to reconnect pretty quick to, hoping to get back in… 
Howdy!
We cover our stance on this in detail Here. What we can focus on here is the crash/disconnection issue here but if you wish to provide feedback on the penalty system that would need to be a new post on our General forums.
When you say crash did you get booted to the login screen or did the game just disappear, crash(With any errors)?
Thank you!
