MMR IS REALLY UNFAIR
This MMR system is so snowball and unfair, when the winrate is only 50%or lower, MMR its only gose lower and lower make low tiers cant get out even they have good skills, I can assure there is somebody in dia or higher is not that much skill-ful ,they are there just because they have a good MMR and not got it by them self. MOST OF MY LOSE GAME IS UNFAIR JUST BECAUSE MMR REBALANCE.
