Rewarding/Penalizing Game Play

I think there is a way to help players in ranked play that would not effect the current system other than to help consistently good players to advance through the lower tiers. Reward/penalize more lp as per your grade you receive for that game. I think this can only be done in the lower tiers (bronze, silver, gold) because once you get beyond that your individual play actually will dictate your advancement. There is simply too much discrepancy of players in the lower tiers. If you consistently get A's or S's for your play you should be rewarded for it. I propose that you receive 1lp per grade level above a B+ (or lose 1lp per grade level below B-). REGARDLESS of a win or loss. For instance if you would normally get 19lp for winning that game and you grade out an A+ you would get 22lp instead. In a loss if you were to lose 19lp and you graded out at an A+ you would only lose 16lp. Now if you gave up or trolled and got a grade of C- it still works in such that if you would get the 19lp for a win despite your play, you would only receive 16lp. In a loss with a C- you would lose the additional 3 as well. I think that a system like this would reward the good player while not penalizing him to have to deal with all the trolls in the lower tiers. Tell me what you think people.
