If Thorzain spends at least 3 months in Korea and goes through the grueling process of breaking down his mechanics and rebuilding them until he has Korean mechanics and high APM, he can become an even stronger player.
Sjow is another player who's got potential but plays with really low APM so he's never going to get to the top tier.
