2 Per Region ofc
You are wrong. Historically Zeta matches are always the most watched in intl matches (after playoffs ofc cos those are high stakes).
Also 70 percent of the peak viewership in pacific comes from Zeta. https://twitter.com/TanmayyMhatre/status/1760859502310756690?t=vN8Z3COWcPnK6Hy-3UbHBw&s=19
Korean teams meanwhile have much much much less fans. Its actually a bit better now, during 2021 korean streams would only pull 10-15k viewers even when drx was playing
NA - Sentinels, Loud (self-explanatory) (maybe you could argue KRU)
EMEA - Karmine, Heretics (TH because the tournament is in Madrid, lot of people will show up in crowd I bet)
APAC - Zeta, T1 (I'm not 100% on T1 over PRX but I think everyone knows T1 just because of Faker)
CN - Edward, JDG (JDG are a big org AND people internationally expected a ton out of them because Rare Atom was kind of going crazy in China)
Americas- LOUD and Sen
EMEA- KC, 2nd team is a tough call maybe Heretics or Fnatic (they pulled a good amount on intl viewership in kickoff while other teams relied more on regional support). Gentle mates would be a good shout too but we already have a French team.
Pacific- Zeta and PRX
China- EDG, other team I have no clue about
