A fix for trolls

So here's the deal: trolls happen. It's never going to change. The tribunal is impotent at best, and nonexistent at worst, and let's face facts: every troll has a smurf account to fall back on. I have an idea for ranked games which could drastically alter the way IP is accrued/lost, and it would help alleviate the headache we all get when some childish little punk gets it into their head to troll. Make IP loss/gain tied to champion mastery score In the event of a win, a higher grade means more IP gained, and a loss would mean less IP lost. And the best part is: an S or A grade would make you exempt from IP loss, or if during a promo series, it would nullify the loss (essentially allowing for a do-over). This system has very little potential for abuse, promotes people actually trying to win, and allows the other 80% of the team to still perform while punishing the feeder/troll.
