Regions (as a whole, not just their best team):
EMEA - Incredible depth, upwards trend in international performances, big player base, and finally varied playstyles. Everything needed to maintain the momentum.
SEA - Massive playerbase, even larger if South Asia is included. Extreme diversity in playstyle - from the overly strategic Paper Rex to the balls to wall, uninhibited, classic SG server agression of X10. The region has yet to achieve a podium finish in true international competition, but there's a real chance they do that now. In APAC, they are likely the best, from the LCQ, and international play displayed so far. Upwards trend, too.
NA - Manages third due to previous performance, depth, playerbase and so far unrivalled investment. NA organizations have shown that they will and can drop the bag to assemble teams to compete in international play (TenZ buyout, Nitr0, etc.). Despite being on a downwards trajectory, it's unlikely the teams ever become truly uncompetitive.
Brazil - Massive amounts of unrealized talent. Large playerbase. The problem here is the lack of investment. Give me a true Brazilian superteam for fucks sake. NIP pls. Imagine: Sacy, Mwzera, Heat + 2 support. With that much individual skill, it's just sad it's not being used well. Below NA, due to a lack of achievements on the international stage.
LATAM - Great players. Lots of talent, and investment to back it up. It seems to be very top heavy though, but that may be in large part caused by my lack of knowledge of the region. Australs, KRU, Lazer if it still exists, and others look strong.
Japan - Big playerbase, investment. Talent is yet to be seen, but some players (Laz, Neth) look strong. To improve, they need to grow domestic talent and stopping importing from KR
KR - Abundance of talent. Not only this, the talent in question has even been displayed at an international level - Masters 2. Lack of investment, playerbase. The problem with this region, and why I'm placing it below JP, is that all the good players will be playing in JP either way, except VS's players.
