Rito Fix Your Game.

FIX THE GRADING SYSTEM.

Make the grading system account for things like stolen objectives (Drakes, Herald, Baron)

try to somehow judge you for how good an assist was. (I know it sounds weird but I mean like if a blitz crank predicts a flash and hooks them then gets an assist, Make that count instead of someone just hitting an enemy once and getting the assist)

those are just a few ways to improve the grading system.
