Yet again AFK's in ranked

So about 8 mins in to a game the jungle leaves. Yet I lose LP for this, it isn't fair! So fed up of people leaving costing me LP this way. I really think there needs to be a set up where none of the remaining players lose LP when someone goes afk in a game for over 5 mins. I took a year off ranked because of BS like this. I shouldn't have started playing it again
