When you get to look at the mastery system

Can you please decide to revamp the judgement system? The current grade system puts like 60% focus on your creep score, and not only that it just looks at how high the number is, and doesn't take into account each individual creep kill. Literally to get an S- or S all you have to do is farm all game and not die, and then you'll have your mastery 6 and 7 badge in no time. I don't get why the system just doesn't look at your gold income, as that's the only purpose you kill creeps, to gain gold and levels, in order to gain an advantage over your opponents.

Let's make a scenario right here.

One game you decided to pick jungle, a champion that doesn't clear the raptor camp or the krugs too well or fast, but you rather focus your power on ganking lanes. The enemy jungler is , someone that power farms the jungle and taxes the lanes to gain a gold income necessary to become relevant, and proceed to demolish your team.

The early game goes great, you gain a ton of kills and your team starts to snowball, while the enemy jungler keeps farming his jungle and tax the lanes you have slain. By the end of the game you've won and have a 14/5/6 score with 160 creeps and 2 tower takedowns at 33 minutes. You have basically solo carried the game, and the majority of your creep farm comes from killing Gromp (1), wolves (3), buffs (1) and krugs after a few items (10). However, the mastery system rewards you with an A+, and you've been halted in your advance towards higher mastery badges. Meanwhile, the enemy jungler spent most of his time farming to get the gold he needs for his items, and finishes the game with a 6/3/1 score but with 290 creeps and 0 tower takedowns. He gets rewarded with an S, despite the fact that he hardly ever ventured out of his farming phase to help out his team.

For some reason this was apparently weighted as a more beneficial performs for one's team, rather than what you decided to do and won the game with. Because was able to clear raptors and krugs more often, he was able to gain a far better creep score as one of these camps carry more creeps in them than the rest of the jungle combined.

TL;DR The grade system focuses too much on your creep score, and not enough on your total gold income and is total garbage.
