By now everybody should be familiar with the story. A player is in promos, and they lose their shot at promoting to the next division because somebody AFK's / DC's and costs them the match.
#Why it hasn't been solved yet:
The main reason RIOT has not done anything about it is because any system that saves a player's teammates from LP loss when that player ruins the game would be abused by duo-queues - leaving or going AFK to save their partner (or buddies if flex queue) from losing LP when they know the game is going to be lost already.
#A New Hope:
What if RIOT implemented a system that blocks a player from queuing up for ranked with any other players if they have had a queue-partner DC or AFK in the past
* < X > hours or
* < Y > games?
This would prevent duo-queues from using leaving and AFK-ing to save one another from LP loss, and it would make it possible to begin protecting players from losing PROMOs because of a teammate DC-ing or going AFK.
