and yet, they somehow ALREADY have a system of measuring individual performance that has been implemented for an entire reason, called "mastery".
It could use some improving, sure. but I sure as hell would rather gain/lose LP based on my mastery point game evaluation score, than the current crap.
Do recall, that while you technically get a "grade", of D,C,B,A,S.... that is only the coarse scale measure. there are actual numbers that get displayed, too.
Maybe they could start a separate queue, the "mastery performance ranking queue" or something, and see how that goes for a season.
Take the mastery points per game (largest I've seen is around 1200), , then subtract 600 and divide by 30.
so, 1200pt score would give you +20 LP. 900pts, would give you +10LP.
300pts, would give you -10 LP, and so on.
Or maybe make it a bit harsher, and subtract.. 800, then divide by 40?
Since only a pure troll should ever be getting numbers lower than 500pts/game
