To be honest, this game has a lot of potential (sc2) but I think there is a lack of talent in the field as of now.
Foreigners often come up with cutesy little builds that are viable for temporary amount of time, but it's progamers in Korea that are capable of making a build/micromanagement that is solid throughout entire game.
I personally think given that top 200 Kespa ranked sc:bw players switch to sc2, they will make up at least 60% of the top 200 list in Korea/world. Their talent is simply too overwhelming.
I think time for foreigners to shine in GSL is NOW. Idra or TLO sure stands out, but I honestly think he will have no chance when any of top 100 ranked Kespa player transitions to sc2 (with exception to fail toss, jangminchul). I almost felt SO happy when I heard some guy named HolyCheck that may either be NADA or BOXER kept winning in Kisado KOTH and the news said that he employed mind-blowing strategies that mirror many aspects of brood war days builds. Those are the faces that I am anticipating to see. Right now, it simply is too painful to watch with amateurs just taking advantage of over poweredness of each race. It's hard to see creativity that can be only sprung from the cream of the crop.
For now, all we can do is patiently wait for bw scene to die. Then Flash and Jaedong will take over, once again. =)
