Can in game performance please effect Gains/Loss of LP?

Please allow in game performance and or grading effect the respective LP loss or gain from wins and losses.

This happens VERY often but just for reference for people to look at for proof my first Nasus game on match history. I went 8-1 in lane, built ZzRot to help with split push while I was massively ahead and farmed to help team win fights to secure the win. My jungler was doing okay and bot was meh, a little heavy of an ADC but nothing too crazy. It was a 42 minute game may I remind you. Our mid is Cassi. in 42 mins with no DCs she has managed to attain 98 cs. She is 0-8 and dealt 3.7k damage to champions TOTAL. What? blink you think I'm joking? an AP mage mid in a 42 minute game dealt 3.7k Dmg to champs. I dealt 42k damage to champs as Trinforce Zzrot full tank Nasus. Also suck Foraka, there's literally no way to deal with her healing unless you 1 shot her at start of team fight.

That's the end of the story. We lost -_-. I lost the full LP for a loss, as did this Cassi. Even if I were to some how miraculously turn this game around and win it, why on earth does that Cassi deserve the full amount of LP for a win as I would have received? She doesn't... plain and simple.

Having in game performance effect gains and loss of LP, I believe would help a lot and even reduce toxicity in this game. It would drastically weed out bad players and boosted players and reward good players who keep their head through a game no matter what. It would give incentive to keep trying and not just GG IM FEEDING LUL OPEN MID 2016 LUL, at any point and time someone becomes demoralized. Feeders are the worst. Its so frustrating and annoying and I honestly have NEVER received instant feed back on someone who was feeding. The person would have had to tell me to drink bleach or to commit suicide or have sexual relations with one of my family members to warrant that. I've had people literally type in chat "enjoy this loss, you don't deserve it bad jungler" and proceed to run down mid lane again and again, or follow me around trying to grief and steal jungle camps only.

Please Riot, do something to clean up toxicity of in game performance. I don't care how many curse words someone typed. If they perform well then GG we win. Literally STOP with this toxicity crusade against simple curse words. There is a chat filter for a reason, and we aren't 5 year olds. Arguably... maybe... lol I take that back, some people have me worried.
