AFKers

Can we please do something about those of us who are plagued with people who go AFK and are forced to lose LP because of it? I mean, I understand that we can report them and they will get a ban, but that doesn't solve the issue of the LP that I lost in that match because of them. There needs to be a system implemented in order to salvage some of the LP that is lost due to people who decide to go AFK.
