If yuor ranking system is 100% broken and deffinetly not working. Meybe just remove mmr from ranking matches??? Jutsm make random silves vs random silvers or random golds vs golds… why you mixing ranks with mmr ??? This game cant by worse. now is completly bottom so this chance can be better.
If I win too many matches alone and my mmr goes up why you punish me after that with drafing worse or worst posible players (or trolls) to my team??? Just remove mmr from system and let ppl selection them self.
