Can we remove hidden MMR?
I know Riot stated ranked changes for next year and testing later this year. One thing that they should start with is removing hidden MMR. You basically get a visible divisional rank but that's not your rank your hidden MMR is your rank that is what matters when matching against other players. By today they removed every way to inspect that rank in the past we could see/calculate it but everyone probably noticed how broken it got so they just removed the option to inspect it probably. The divisional system was introduced 9 YEARS ago. The hidden mmr was probably a leftover which made it easier to change to the new. For 9 years they added sutff on top of it breaking it more and more. One example, if you lose a game at 0 lp while you are protected, that's the worst. When you win you gain mmr, when you lose you lose mmr. But at 0 lp if you lose you don't lose rank only mmr. This makes your mmr shifted compared to your rank. The opposite is not true as the average mmr for higher tiers is higher that you get for placement wins by climbing there which again shift your mmr below your rank, FOR RANKING UP. Now if your mmr is lower than your rank the game automatically thinks you are at a higher rank than you should be so it will try to push you down, but remember your mmr never increases only decreases compared to your rank. The only mmr increase compared to rank I could only see with huge win streaks which becomes rare at higher elo/the harder it gets (even a challenger loses diamond games consistently). What lower mmr than rank causes is just a speculation as I said you can't measure it but I noticed that most of my lose streaks start after a 0 lp lose and you probably will get less lp for winning lose more lp for losing.
