1) MY/SG -Paper Rex are currently the best APAC team until proven otherwise and Bleed/Gaimin are both strong competitors
2) ID - Improved a lot this split and have two strong teams (ONIC and AE), with BOOM being just a tier below them
3) TH - Used to be the undisputed best region but has looked shaky this stage, XIA is their only solid team right now
4) PH - Region has tons of org support but the teams are just mediocre. Aside from Secret, I think the region just lacks experience
5) OCE - Order are super strong and I think BOBO has potential if an org like RNG signs them
6) VN - Big BAAM looked like the worst playoff team but Fancy United and Cerberus are alright
7) HK/TW - Has potential if it gets more investment, players like 8lua deserve more opportunities
8) SA - Pretty self explanatory, their teams can't seem to stop choking and somehow GE keep winning domestically when OG and VLT looked better imo
TLDR: MY/SG > ID >= TH > PH > OCE > VN >= HK/TW > SA
Rankings are based on a mixture of both quality and quantity, which is why a region like ID is higher than TH even though XIA have a good chance to be better than ONIC
