Not a major event either. Maybe the final will have more viewership since it's the last team to qual. Most of the viewership is NA based in this event.
I think theres a lot of things, like halloween weekend, CSGO major, first year of valorant, plus a lot of people will care more about the finals since is only one team that makes it.
I was kinda surprised as well to see the number when lcq started. I guess the taste of international competition made regional competition less exciting.
