Pro League of Legends player Marek "Humanoid" Brazda had his word on the NA LoL scene in one of his twitter posts. Since the start of the year, players and casters complain on the NA scene a lot. There have been thoughts even that Riot should not organize another Worlds in the US. And this is Marek's take on the current level of Solo Q play in the region:

Players notice such difference when they move from one region to another. But Humanoid has mostly been playing for EU region. He has been a mid laner in Fnatic since January 2022. The roster placed 9-10th at Worlds 2022, so he experienced the bad solo q during the practice time in San Francisco.
