Winning and losing LP
The current system is stupid.
A win or a loss should award or take away LP.
For example you lose a match and you lose 17 Lp.
But say you played at an S level...it should be reduced by half.
Or if you win, and you gain 22 LP, but played at an S level you should get 33 LP. Or if you win but played at a shit level, did pretty bad, you should only gain 11 LP. Obviously there would be a range.
Individual performance should adjust LP awarded or lost. This will help players not feel as powerless in bad matches, and incentivize players to still try their best more often instead of just losing hope and mentally checking out of the match.
Because players have more control over the outcome, there will be less toxicity as well.
If I play like a god an only lose 10 LP because my team was awful...well, I am much less likely to rage.
There is literally no reason that Riot shouldn't implement this. But I'm sure the troll Riot fanboys will give me some reason. Lets hear it.
