dear rito, can you at least improve the LP gain/loss system a little bit

I am in D2 and I can understand in upper leagues players lose more lp finishing 8th place than they gain finishing 1st place. However it is really overweighted atm. I lost 28lp for finishing 6th place, and gains 26lp for finishing 2nd place. I lost over 60lp in a single game finishing 8th place. And even if I get 2 straight 2nd places that does not grant me 60lp. It's not easy to finish 2nd place in diamond games. It feels like I barely get rewarded for my good decision making/good luck etc. and get punished extremely severely for my bad decisions/bad luck. To me it feels like the best thing to do to remain my rank is to not play at all. Bc if I perform averagely in a D2 game I will get demoted. If I perform significantly above D2 I can barely remain in D2. And I have to perform significantly above D2 skill level to climb up in rank at all. That means one's rank does not reflect his/her skill level. How does this LP system even make sense?

In TFT, hard work does not pay off, but instead harms you. If I perform My friend and I was in D1 weeks ago. He was frustrated by the LP system and quitted playing. He has only played 200 ranked games and still in D1, I played 600 ranked games and now almost demoted to D3. Since he's ranked above me, the ranked system suggests that he's a better player at this game. How does even make sense at all? The more I play the more unskilled I become? Why would I ever play another ranked game ffs
