So far, how many times has Riot rocked the MMR boat this year?

Here's my count:

Positional ranking removal (gave people who played more than 1 role an MMR Much lower than their primary role rank they were given (Some cases, 5-6 tiers difference between the two, destroying any possible LP gains simply by making you require 70-75% win rates just to maintain your rank)

Kayle/Morgana (Mostly Kayle) Initially made lane phases weaker at the beginning, but created an unstoppable machine once level 16. Win rate/release exploded for both champions.

Yuumi: Popular pick, even though she had an initial horrible win rate. Not the best champ for TEAMS to learn to play with, and actiely shoved MMR's down simply by being picked.

Mordekaiser: Ult going to fundamentally change the game. Going to increase his play rate by 5 fold, and probably lead to MMR increases for some players just for picking him, and MMR losses for players losing hard to him while learning to fight against him.

Qiyana: Yet another champ introduced only 3 weeks after Yuumi release. Looks to be sleeper OP, but hard to tell. Lots of damage enhancements in the same kit, a stealth option, serious CC (Push back, Root), massive aoe ult. Hard to tell how she's going to affect MMR, but generally, new champions always destabilize LP gains/losses simply by being picked.

This isn't even mentioning Yi changes, Aatrox changes, Jax with Shojin's, etc.

I do generally think though; players are not keeping up with the changes, which is a signal Riot is going too fast.
