Assuming you don’t have any connection issues or bugs, the likelihood of having an afk/disconnect on your team is (proportion of players experiencing connection issues) multiplied by four (for every player on your team excluding you)
The likelihood of having an afk/disconnect on the enemy team is (proportion of players experiencing disconnection issues) multiplied by 5.
In other words, if you take into account every game you’ve had with league, every 4 games you have an afk/disconnect on your team, you have had 5 victories owed to disconnects/afks on enemy teams.
So, if you get these league points back, are you going to give up the league points you didn’t rightfully earn?
