Individual lp gains and losses
New rank system that no longer rewards or punishes the whole team overall. Someone mention grades but grades take in account base not on how the game went but based on how others of said champion played per role. So imagine a thresh sup goes 2/0/20 and another thresh sup goes 4/9/10 the ladder would get an s while this thresh might get a b. That's roughly how it works.
Now a better system is to grade based off of how u did win or lose. Laners top mid and bot how was your cs get a 5 for perfect cs get a 0 if below 100 Cs by 20 minutes in game.
So this is how it would work
Top lane mid lane bot lane jungle support
Cs perfectly get a 5 do poorly get a 0. Take tower vs lose tower determines if you won your lane. 5 points for winning 0 points for losing.
Jungle and support criteria at bottom of this post
Everybody graded system
Vision score place wards that caught enemy champion destroy wards to deny vision more wards placed and destroyed you do second best on team get 5 points u do worst get 0 points. Overall kda 100% means 0 deaths or 2 to 1 ratio get score of 5 compared to no kills or 1 to 2 ratio gain 0 points Kill participation 100% get a five 0% get a zero Objective control rewarded 1 point for each objective you participated in.
Roles specific
Now tanks tank most damage get 5 tank least amount of damage get a zero. Note a tank will be only eligible if riot considers them a tank and tag them as such . Ex garen Darius nasus sorry gragas and reksai
Adc and apc do most damage only eligible if marked as a marksman or mage adc attack damage apc magic damage. Do the most damage out of mages get a 5 or do the least magic damage get 0 points same goes for the adc.
Bruisers graded on both ability to tank damage and do damage only eligible if considered a fighter and marked as such. So ex. Vi took 26k damage and did 20k damage and the tank took 50k damage and the adc ditched out 50k damage this vi would get a 5. While if she only took say 9k damage but ditched out 16k damage she'll get somewhere in the middle of 1 through 5.
Assassins measure on kills 1 to 1 ratio gets them a 5 while anything less would get them a 0. Assassins are graded harshly because of their high risk high reward playstyle.
Jungle
Graded on possible camps taken through first 20 minutes of game more camps taken more likely to get a 5. Take little to no camps get a zero. Countering jungling if u took last minion in camp u took the camp. Ganks success for each attempt get a flash kill or assist get a point lose a point if you died with no kills or flash for a flash.
Support
Assists solely getting the most assists in the game will give support a 5. While getting the least will get a zero. Supports are expected to ward more often so because of this they are expected to always place the most wards that spot an enemy and deny vision. They'll get a 5 for this while they'll get a zero for not warding the most. Bonus given for destroying hidden traps like jhins stealth bombs or teemos mushrooms.
This is if your team wins get perfect score in every category get 30 lp gain Do the worst in every category you'll get 5 lp gain.
If your team loses do the best in these categories you lose 5 lp. Do the worst in these categories lose up to 30lp
This is all regardless of mmr win streaks or loss streaks.
