Individual performance SHOULD matter in Solo que.
As a support main, it’s not fair that I’m only as strong as my ADC. If I get a shitty ADC it doesn’t after how well I support him. 90% of the time it’s a loss. Now I think it would be nice if your contributions to the game actually had some impact In gaining or losing LP.
For example, if I lost a match with a score of 0/2/22, warded well, roamed, assisted in baron/dragons/tower, and had a nice gold per minute, I definitely SHOULD lose LP but I should not lose as much as our 0/10 yasuo top who keeps going in 3v1.
