3 v 5 LP crapshoot

Hey so I don't usually complain about unfair games because I honestly believe that one can always improve their skills to make a game equal. That said, I have been stuck in a spiraling issue in ranked que. I am currently ranked Bronze III (which I find does not accurately reflect my skill level, but that is beside the point) and my issue is that I am constantly qued in matches where one or more players feeds or outright quits. Now I realize that specific policies would be difficult to enforce but I don't believe I should be losing upward of 20 LP for a match where 2 of my teammates leave. I think it would be beneficial to implement a system in which the amount of LP you lose as a result of a game decreases as people leave the game. That way players such as myself are not trapped playing worse and worse games as we lose games as a result of feeders/quitters. Additionally, this problem could be solved by in-game reporting so that players can be punished directly after their behavior so that teammates don't have to spend 20-30 minutes putting up with a negative, feeding, or quitting player. I respect that the rankings are suppose to reflect talent but in this case I don't think that is really whats happening, it more so reflects luck.

Anyway, just my thoughts Kage no ken
