A serious problem that needs to be addressed, but won't be

If you are playing your qualifiers in ranked, and someone goes afk the entire game, the system needs to be able to detect that (as it already can in order to penalize afkers) in order to forgive the loss. This game was meant to be played 5 v 5, not 5 v 4. It is actually quite simple. Riot, do us a favor, and do not penalize loyal, paying customers, when something out of their control occurs. Not only would this be fair in the interests of preserving your clients, but it would help make the community less toxic.
