Too many complaints about matchmaking are stupid
Seriously, lately all majority of the thread on this forum are regarding “bad” match making.
Now, I think we can all agree, the match making bad problem. Mostly, I believe it stems from players who are forced to role (auto fill) that they don’t know how to play. Obviously, if you have little experience in the support role, you will likely lose (in lane) against a player of similar rank as you experienced in support role
Outside of the auto fill, many of the issues just stem of playing not understanding how to lose without feeding. Good players lose lane, giving minimum to enemy opponent. Others lose lane as a spiral where they only go back to lane and end up dying repeatedly.
There is a small problem with smurfing but that’s mostly community issue not Riot. You can’t blame riot when players in plat (or above) complaint match making when some of these players purposely smurf through lower ranks
I don’t see a huge issues of (gold to bronze) match making. I understand the issues on plat and higher potentially being more severe.
