There really needs to be a rating system to reward consistently good play in ranked
Players who consistently perform poorly when they lose games should be penalized beyond the standard LP loss. Players who consistently perform well, even when they lose games, should be rewarded in some way.
The current system for solo queue isn't sufficient. There are so many players who single handedly lose the game for the rest of their team, because they have a poor start, stop caring, and basically just feed the other team for the remainder of the game.
These players aren't penalized any more than the team mates who were unfortunate enough to have them on their team, which is nonsense.
