Match elo with elo, not mmr.

More of an Explanation would be better than "Stupid fucking matchmaking" that way your point gets read instead of instantly downvoted. But i do agree that the Mmr matching throws me off frequently, i ussually get low silver on my team with a gold 5 or 4, and the enemy gets 3 high silvers and 2 gold 1s. Im not this good, my mmr is average or slightly below average unless i go on a winning streak, which means one of my teammates must have a high enough mmr to matchup against soon to be plats while being in silver

No, I do not want boosted players in silver 5/ gold 5/ plat 5/ diamond 5 play with other players who actually belong in the tier. Once they finally get demoted, they'll play with people near their skill level while gaining less LP when winning and losing more LP when losing.

There are a lot of issues with the ranking system but what you are talking about isn't really the big issue. Matching MMR isn't problematic, it's how they match that MMR that is.
