Loos prevention
As a ranked player I experience many things, some good others bad. Probably the most detrimental however would be d'cs. I don't care if you have a bad game, I don't care if you get frustrated as long as you still play. But if you afk you basically guarantee that your entire team will lose.
onto the topic of Loss prevention. I don't think that it has a place in normal's at all but in ranked there needs to be an automatic loss prevention. If a person is disconnects for more than 5 minutes loss prevention should automatically occur. Riot you would then ask how do we ensure people don't just afk because it looks like they will lose. The answer is simple the person who afk's automatically loses LP while the rest of the team receives loss prevention. while I know that you have time bans and low priority queues for people who afk and dc but that doesn't change the fact that the good players are being punished because of one person.
losing a ranked game due to a dc is not right and in order to be fair to all parties the players who stayed and tried their best should not be punished for others not staying or having faulty equipment.
