Koreans just aren't interested in Tier 2. Why would they seek out Tier 2 when they can bask in the glory of Tier 1? They're even more cold-minded than Riot itself, who ruthlessly abandoned Tier 2 because they're only interested in highest level competition. The same goes for wages. Koreans understand the fleeting nature of E-sports hype better than anyone else in the world, and in fact, Tier 2 players are paid accordingly.
