Client has been crashing lately
I've noticed at various points in champion select myself and other players seem to crash. I'm guessing the client makes no decision before deciding to punish the account with a dodge ban. I get caught up in fearing this type of stuff because of the "behind the curtains" approach Riot takes towards automated suspensions.
Although I'm not a player that flames or excessively dodges, I have certainly felt the pain of 10 minute ques in the past.
