My feelings on how ranked should work
Keep in mind this is just an opinion please don't get triggered if this idea doesn't feel right to you I feel ranked is a coin toss you can have 4 people doing well but 1 person doing horrible that costs you the game so its just a coin toss on who gets what teammates and I don't think its fair you can gain/lose a fixed number of lp based on your mmr I feel that you should have gained/lost the mmr's fixed amount BUT depending on your performance you either get extra or less Ex: I won a game and my mmr will earn me 17 lp however I did really poorly going 2-6 so I lose 4 lp leaving me with 13 lp the same goes for a good performace adding lp to the fixed amount that your mmr will earn you.
Original idea came from this thread https://boards.na.leagueoflegends.com/en/c/gameplay-balance/v22hexhU-why-ranked-is-fd-up-according-to-diamond-player
