Factor in KDA in LP gains/losses

If you perform exceedingly well - ex. solo carry your team, you should get up to 5 bonus lp points, mirror for if you go 0/19, you lose more lp than your teammates. Probably this idea has already been around and excluded for some reason, but that would clearly 1- eliminate the need for ppl to cry "report inting inter" and 2- ppl who do better/worse than their teammates would end up in their proper rank quickly. Maybe this would change the game in that ppl would go exceedingly turtle to not have the worst scores and stuff, but if LP bonus/penalty is small, then it might not. Would like to hear what ppl think about this. GG WP!
