Why am I banned from arena & ban time doubles ?

I quit arena games when my team isnt supportive or I get left handicapped , I keep getting banned and the duration of the ban doubles every time. This is ridiculous that I can’t play a game I paid for, have to wait 8 plus hours to play a match again for quitting infection? And the idle time to get kicked is too short. How does the system base how long you’re banned for?

Hi OP, please use the ban thread pinned at the top of the forums if you need help with matchmaking bans
