I quit League Of Legends today. RIOT just fix one thing for others

I started lol in s7. Friend gave me acc with bunch of champs on lvl 30 so i can start. This game used to be fun when i started. I played mid, top, jg with my friends. When i got better i started solo q and started to rank up. I always was in gold from the start and peaked in plat at s7. I think i'm not the best player nor the worst, i deserve high gold or plat, it is my rank. Games used to be fun> you either win or lose lane(sometimes get camped 24/7 and still menage to win)>take objectives, items, help your team and win or lose. But you still got huge chance of comeback if your team or you lose in early game. Recently i was gold 1 94lp and i was playing top lane(i love fighters) and i had 70% win rate on my trundle, irelia, swain and i win my lane in 90% of matches. When i got to 94lp gold 1 the nightmare started (i got plat 4 or 3 MMr at the time). I started getting team that lose lanes in under literally 5 or 10 min(just feeding mindlessly). I was on huge losing streak and i was like ok maybe i was doing something bad(i was losing my lane too sometimes, can not win always). But things just went on and on and on> people started inting>feeding> going afk almost ever 2nd or third game. And that tilted me so much cause it is never loss prevented if someone tilts and go afk and you are left to fight their fed carry 4v5(i know how loss prevented works, i'm just saying it is not ok for someone to lose lp just cause of someone else decided to leave everyone in ranked to 4v5 or his net went down> NOT FAIR RIOT). I switched to playing normal games and stopped ranked(told my friend he can play it if he likes, im done with it> very toxic community and very bad matchmaking). I started ranked again in s 8 when i took acc again after my friend finished promos and few games> acc was in s3 or 4 and i got it in gold in no time(few days). Again peaked to g1 and went on losing steak. I ALWAYS got feeders(very hard feeders (feeding mid, or carry under 5 min very much it is not able to recover)) and almost every game i had really bad mid or bot, so i decided to switch mid and have more impact on whole map(spoiler> i did not). I had 70% win rate zed and was doing decent job at pushing in lane and roaming, taking objectives . I could not have impact on Almost every game> my bot giving carry double 2 times in under 5 min, top lane giving first blood > continues to fight non stop and die. I AM SO TILTED OF THIS GAME AND HOW SYSTEM WORKS. I'M SICK OF PEOPLE FEEDING AND I I CAN NOT DO ANYTHING ABOUT IT EARLY ON CAUSE THE GAMES NOW LASTS AROUND 25 MIN AND YOU ARE DONE IF THEY HAVE FED MID OR BOT IN FIRST 5 MIN. You never get loss prevented or something when someone goes AFk in first 5 min, you are just tilted and angry cause you know you will lose lp unless enemy team are really bunch of retards to not win game 5v4 with fed mid or bot. This game is not fun anymore. It became game full of oneshoting, hard snowballing and full of players who will just insta lock some weird stuff and feed cause they saw a youtuber did it and it worked for him. RIOT i ask for just one thing( i'm still going to quit the game) >>>>>>>PLS make loss prevented system so people do not lose lp if someone just decide to leave the game and lave whole team to lose LP. It is so frustrating. Good luck to anyone who still play this game and will continue so. I wish you all luck in anything you pursue in your life. I'm out, peace. :*
