Issue/Suggestion: Afkers/leaving game in rank

There needs to be a system set up so when someone is afk/leaves game in a rank match that person takes the lp lost, or the group can forfeit without lp lost. I just was on a 4 win streak in rank, then 2 afkers ruined my match and I lost 22 lp from it. One of the players reconnected after 10 minutes but the match was still a 4vs5 and was an easy win for the enemy team. I would like to know feedback on this issue/suggestion to improve game enjoyment and help people further their ranking. Thank you for reading this and have a nice day.
