I'd say underrating KR/JP and overrating SEA. Problem with KR/JP is that they have one team that they send out lol, ofc they won't have multiple teams doing well internationally. VS have just always had a shitty group stage or did better than most of APAC though usually, and if you want to go off of improvement, JP are the most improved, from masters 1-3 u can see CR and ZETA just getting so much better.
I'd honestly go with EMEA, NA, BR, SEA, KR/JP.
I think the judgement that KR/JP are one team regions is kinda dumb bc they literally can only bring out one team, and for the majority of JP's history, they haven't been a one team region. KR are also are definitely not a one team region, Nuturn bringing down VS and just Damwon, ONS, TNL, I don't think KR are a one team region anymore.
Or more like EMEA, NA, BR, KR, SEA, JP, LATAM, SA. KR just had an unfortunate Masters this time imo.
