Those being BDD, Faker, Showmaker, Zeka and Chovy. Here's some more fun facts.
Total from each region:
LEC: 10 (Nemesis, Caps, Humanoid, Larssen, Nisqy, Nuc, Fresskowy, Poby, Jojo, Kyeahoo)
LCS: 15 (Nisqy, Damonte, Jensen, PowerOfEvil, Bjergsen, Abbedagge, Perkz, Jojo, EMENES, Palafox, APA, Quid, Quad, Saint Loki)
LPL: 11 (Doinb, Rookie, Xiaohu, Yagao, Xiye, Angel, Knight, Scout, Icon, Creme, Shanks)
Of these 36, 10 are Korean.
The LCS has sent more Europeans and Koreans than they have North Americans.
Also remember LCS and LEC has had less seeds at worlds, and even then they still have double(or triple) the representatives.
I think this also brings up a big question, with many Korean mid prospects continuing development in other regions, what will happen when some of the veterans retire? Will Korea maintain it's dominance without the big 5? Will it be the league of Zeka/Chovy?(It kind of already is)
Faker (30) , BDD (27) , Showmaker (26) , Chovy (25) , Zeka (23)
