Every time I see a thread about a team picking up a Korean team. I instantly see someone say that Korea is better automatically.
Yes, South Korea is a very good team, the best in the world. But let's not talk about 2016 OWC because the game wasn't out for very long and it was just getting into the esports scene. Now as we enter the next year a lot has changed- 3 new heroes, 3 new maps and tons of balance changes. Everybody seems to know the game a lot better than they did back in 2016.
In APEX season #2, EnVyUs finished 5th, while some other NA team finished 9-12. But the meta was shifting by then, triple/Quad tank was dying and a new meta was beginning to form. This, of course, marked the end of the first EnVy reign. In APEX season #3, Rouge was at its peak but the Dive meta was again, beginning to die and other teams could simply play Dive better than Rouge, who fell off the map and finished 9th, EnVy finished 4th. NA teams Can do well in Korea.
Now because of OWL things have changed, These 12 teams are basically all-star teams, with Dallas signing some of the best players from around the world to bolster their already dominant lineup, LA Valiant signed SoOn, Unkoe, Numlocked, Space, and Silkthread to bolster their already very good lineup. And SFS had quietly built up an incredible DPS roster. There used to only be 2-3 really good players per team before OWL, now all those great players will be combined on one team. Korean teams shouldn't be as dominant against these teams.
In Korea, there are about 12 relevant teams, in China there about 6 (haven't watched much Asian esports), Taiwan I believe there is two, One in Australia and Oceania, NA there is 10(ish) and EU there is 4. While Korea is a small country, it still has a ridiculous esports following and has so many players, but these are all spread out among 12 teams, approximately 72 great players. Adding all Non-Korean teams together- you have 20 teams and 120 players. My point here is, players in Korea are not as spread out as other regions.
In conclusion, South Korea is the best Esports Country in the world, yes. BUT, A team of Koreans does not necessarily mean that they should beat a very good NA team.
