Riot admitted their mistake with positional matchmaking, that's great. However, their revert has turned into a mess. MMR got send all over the place for many players. Even though players got their highest positional rank, their mmr from other lanes also merged into their highest position's mmr. This causes changes in LP gains and losses that are different and potentially very frustrating. I was gaining 22LP for each win in my highest position. Now, however, I am only getting 16 LP per win after revert.
