MMMR is Retarded!!! Broken

MMRs on 3rd party sites are known to be very inconsistent.

Your performance in game has no impact on your mmr, only whether you win or lose.

Additionally, third party sites can only guess your mmr, they don't have any way of knowing for sure, and as such you can't know what your mmr is or how much it changed after a match.

We won, But I was using a third party website anyway to check my real mmr?

So real question here, If I Win can I actually drop mmr?

{quoted}

I went 0/3/27 as soraka support and My mmr dropped by 20?? What??! 9.0KDA and my mmr dropped

Only winning and losing affect your LP or MMR. It would be way too subjective otherwise.

Did you lose the game?

did u win

did you win? are you basing this off of a 3rd party website that doesn't necessarily have accurate mmr? how many games have you played?
