Wonderful having a ranked 2v5

I'm curious, why do I lose 16 LP (my average LP loss) when not one, not two, but THREE people are afk in a ranked game? Unless you're telling me that a non-premade group is going to have 3 people dodge to make the others not lose LP or have less of an LP loss before the game's anywhere near decided, there should be an LP loss reduction with afks. Even if it's not in premades where it is abusable, this should be added in already. It's long overdue.
