Almost every second Korean player is cracked, probably the most stacked tier 2 in APAC
Some MYSG rosters are good
PatrickWatson and Papichulo are probably the best PN tier 2 players (talkin' about so far, I don't know how they will do with GE)
Lots of Koreans in Japanese tier 2
South Asia probably you have heard of Venka and Techno at some point from South Asian users on this site
I can't remember much at this point but uhh these were just at the top of my head
