They should just merge and make APAC North and APAC South like apex no cappa
I Will explain to you because it's too hard for your mind
Korea is a pretty heavy strategy based/utility scene, yes they have really great players but the core Sense for Korea is skill usage and intel.
Brazil doesn't have the needs to develop a counter strategy to destroy and Deal with Loud aim Star selection by now, that's why DRX and other Teams are important to be faced by Loud.
This Teams are the only ones that have the sufficient knowledge to play a game countering the core aspects of Loud and their game, because of the insane playbook that Korea has at it's own scene development, that is different from a heavy aim scene/ Less strategy like Brazil.
For Loud to evolve to New levels they need to play against this different types of playstyle from each region.
I've chosen Korea because they are much more interested in skill usage and Less aim based games, hitting a level that BR never faced before, and creating a problem never faced by this team.
They need to be countered by DRX so they have a chance to evolve to another level by overtrowing this problem. After this they Will bring this Tactical knowledge to Brazil making the scene hit a New high of intelligence plays around the scene, something that i really think is a stuck aspect in BR right now.
This would make the entire scene stronger because they would learn How to play against this type of team that they right now have no needs or capacibility in How to Deal with.
This happenned After VKSxSEN, VKxAscend and etc.
That's why i need to Korea to face Loud for me.
