major region - a region where are contenders for tournaments in the past 12months like EMEA with FPX FNC (maybe TL, maybe not) or NA with OPTC,100T (maybe XSET, maybe not)
minor region - a 1team region like APAC or BR (sorry brazilian fans but no tier 1 team other than LOUD)
and i want to say that jp is in the middle, they dont have good tournament contenders but they have 2 teams fighting for one spot for a tournament with NTH and ZETA
LATAM is the best definition of a region changing from minor to major with KRU becoming better comparing them to their 2021 form and LEV being beasts out of nowhere
