Rito Score Processing Broken

Hello.

I'd like to know how the hell can you have a S rank, since it's not explained anywhere, the equation isn't given. Where is the transparency riot?

Look at the game I'm posting with this post, how do you not understand players being frustrated with not having the rank even with this kind of score, gold and co? The stats are largely over the others from this game.

How can I not think your rank processing is broken?

At least, give the clear variables impacted..
