If I get an S in a lost ranked game, I should receive a smaller LP reduction than normally.

Games like the one I linked seem to happen a lot, and it really feels bad when I do the best on my team (objective control, gold obtained, kills, most dmg dealt to champions) and receive an S-, and still get the same LP lost as I would if I was my nami who went 0/7 with virtually no objective control and ran into the enemy team blindly in teamfights several times. I'm not saying I'm a better player, and I'm sure as hell not saying I deserve a better rank than what I have. I just think I deserve less LP lost if I do the best on my team.
