How to work with MMR and LP losing or Gaining

So this season, everyone start off earning big time LP from 25LP for most Bronze to Plat and 25-35LP for Diamond+

It doesn't matter if you started your placement horribly this season going 1-9 or 0-10 which is the worst, but because of this season how you're able to earn 25LP from the start, this help most players rank faster not easier but faster.

Because it always base you on higher MMR pre 100 ranked game, once you hit 100 ranked game your MMR actually start to click in making you earn your actual LP you should be earning or earning less and losing more as well. So basically for me this Season riot has given everyone a much higher chance to gain more LP than any other previous Season

Also in 2015 I think, they implemented the "Free Win" for Bronze-Gold" when you enter your series or promotion matches except Gold 1 you don't get free win in your series to Plat.

MMR

So about MMR. Back in Season 4 or lower, riot has a ranked tier restriction they use that don't allow 2 tier differences to play together. But now, if you're Plat you will get que with Silver, if Gold you get que with Bronze, etc.

Having high MMR already allow the players to earn more LP than lower MMR players, but that's not enough they get que with higher elo players. For god who know, maybe they're getting carry because they get to play with higher elo players making their MMR better

Riot need to understand everyone got to their elo or rank for a reason, either is cus they got boost or they actually play their way there fairly. Gaining very little LP is hard enough for having a shitty MMR, and gaining so little. Once you hit that shit MMR, if you win 2 game and lose the next one? You lose all the LP for those 2 game. How is one suppose to fix their MMR or climb back up?

Especially how is one suppose to climb back up when they get que with bunch of silver because they're Plat with Silver MMR? And not just that, they get bunch of Silver going against bunch of Plat on the other side. What?! Shouldn't we be playing against Silver as well if we're getting que with Silver? But no you get to play against Plats with your silver Team.

LP Gain & Loss

So the LP gain and loss is base off of MMR as well and nothing else but your "MMR"

I was thinking what if we expand the LP gain and loss in a different way rather than just MMR. Since we have those S, A, B, C, etc grading system on our performance, what if those performance help us gain and loose LP more and less.

Its hard to earn an S being on the losing team even if you go 10-0-0 KDA with a good csing of 100cs per 10min

So if you earn an S grading you should be earning at least 3-5 extra LP for performing well or losing 3-5 LP less for losing even tho you still did well. Maybe this would tilt players less even if they're losing knowing they still did well losing. Because most of the time, alot of players are just losing their LP because someone on the team is inting or legit just bad or troll
