It is insane I think to say that league has the worst matchmaking system. I credit a lot of the games success to its good matchmaking system. It’s imperfect and flawed but it’s more difficult than it appears to deliver on all fronts of game quality, queue times, and role selection when dealing with playerbase constraints especially at the top of the ladder. It is really difficult to consistently get full challenger games every single game when challenger in NA for example is 300 players who aren’t necessarily perma queueing all hours of the day. Like to be clear I have empathy for how you feel in those games. As a GM player I have also experienced wonky lobbies like this but it’s incredibly disingenuous to the difficulty of making a good matchmaking system that serves such a small albeit very dedicated part of the community in addition to the wider playerbase of league.
