The letter score system in endgame is flawed
I've noticed it more after I bought the Worlds Pass, but sometimes i'll do extremely poorly and get an unexpected S, which is nice. Other times I do amazing and I only get an A or and A+.

It's not the end of the world that I didn't get an S for the first game, but it's just annoying how Riot created the Worlds Pass around the idea of the score system, and it doesn't work like it should sometimes.
