Is there anywhere rating scheme is explained
I'm trying to understand better how the rating system is calculated.
The other day I played lee support @ 2/4/25 received an S-
Our mid Cass went 19/0/11 received an A+
Our adc went 11/2/15 received an S
Cass had highest damage on team most cs and best KDA yet did not receive an S
every time I think I have this system figured out there is a game like this where players who should get an S+ receive A+ and honestly for this game at most I deserved an A+
as far as I can tell though some things that players don't take into consideration are wards placed, (so players not buying pinks and or using trinkets) wards cleared (supports not sweeping or junglers not using raptors to clear wards), and major objective participation top and mid laners not assisting with dragons, or turrets.
of course I have no clue and have not seen a post that actually explains the factors actually calculated into this.
