Wouldn't it be cool if your mastery grades affected how much IP you earned?

S- could be a 1.25x added on to the ip earned, so if you earned 85 ip, then earned a s- grade and multiplied it by 1.25 so you end up with 105 S could be a 1.3 S+ a 1.5 obviously i'm being generous with the bonus ip but i think it would be a nice idea and reward those who are skilled, since if you main a champ mastery grades become pointless because you already hit 7 on it.
