The LP Gaining

Right know league games go like this you feed then you get carried and you win , you do well your team does bad you loose , you are doing well your teammates are doing well you stomp or you are all doing bad and you are stomped there are rarely close games. In the end you gain and lose the exact amount of LP that your teammates win or lose . Its a team game but you should get rewarded for playing better then the others. If i could change something it would be the LP each player gets. You play better then all of your teammates but still looses , you will lose less LP if they lost 19LP you lost 15LP and if you won the game but someone is doing poorly he gets 17LP instead of 19LP. The MMR system is good and if you add that LP system it will reward better players without punishing the bad ones too much. And the way the the system will tell who did well is by the damage done healing done towers taken gold income shields cs longest cc time and so on. I think its going to be a neat way to reward players for playing good and winning laning phase mid game or late. These were my thoughts on the LP system right now . Comment if you see it useful ,if it needs something else or if it will be useless and bad in general.
