No loss of LP when you score S Rank or higher in ranked.
I think it's fair to say that when a team losses not everyone deserves the loss. If a team member of the losing team scores a champion rating of S rank or higher then I believe this person doesn't deserve to lose points for that game. The S rank is based off of many factors and shows how well a player contributed to the game in a majority of it's aspects. S Rank is very hard to achieve, even when you are on the winning team.
It's my opinion that this is worth looking in to. Am I the first person to think of this and post it? Has Riot thought of this themselves and dismissed it? Would love to know everyone's opinions on this topic.
