Can we implement ranked bans?

Please, I am getting very annoying when 1/3 games someone goes afk and then everyones time is wasted because the game is obviously won 9.5/10 by the team with the afk, and the games aren't fun to play out. no other game goes this soft for going afk in a competitive match. Overwatch would heavily tank your SR and give you a leaver buster, but if you afked multiple times you'd get ranked banned for the season. CSGO if you go afk you lose the match and your skill rating and you cant play for about a week if you afk enough.

      Pretty much what I'm suggesting is if you afk more than 6 times in 3 months in ranked you're done. you can no longer play ranked for those 3 months and then every 3 months it resets.  This can stop afking and start punishing players harder for doing it.
