i think a problem with crowd perception recently has been the home team doesn't have a team to support. CS dallas was crazy cause stewie being NA hero in the finals. Rn they're playing in china with zero home crowd representative plus cultural differences when it comes to crowd/audience etiquette
there have been some good crowds in Valo id say champs LA with eg the crowd was pretty good (although definitely a lower level than cs) as well as LOCK//IN brazil
also riot markets the game real differently, like the "f apeks" chant would never be allowed on a riot broadcast just cause of the nature of their brand and sponsors
