Regions as a whole its definitely
APAC > AMER > CH > EMEA
APAC and Americas are very top heavy with realistically 3-5/12 teams being international contenders, where China has 1 superteam and 3-4 really solid teams that flip flop on who makes it to internationals that dont have enough experience yet to be serious contenders (beyond WOL cinderella run which is basically Zeta 2022 Reykjavik over again)
EMEA has FNC which would be a top 3 in any region and then like 5-6 middle of pack teams with some major shitters near the bottom
