We heard from many progamers and other guys in the scene that talent is often kind of overrated and practice is the most important thing to get really good at Starcraft. But Serral being so much better than any other foreigner seems to kind of contradict this maxim.
We know that the player base in South Korea is much bigger than anywhere else. So the likelihood that great players rise from there is just a logical consequence. So could it be that we just almost never had such talented players in foreigner land like we always had a handful (or two) in South Korea? This is nothing new and the obvious counter argument would be that all foreign players combined should be as much as korean players and therefore there should be the same probability of some great talents to touch the game. So the main factors for South Koreas success must ly in their superior infrastructure and training regimen plus the density of so many players in such a small region which boosts competition, right?
But we know from the region lock that tough competition is not always the best thing to grow new talent. The region lock helped foreign talents to flourish and some new talents arised. The big competition hindered the somewhat talented players to be successful and become better while achieving that. How many of those somewhat talented players do we see in South Korea? The GSL Ro32 or former upper half of code A material? More of course but not that much more. One would assume that with the big South Korean player base (which is probably far more intrigued to compete than the foreign player base because it's probably impossible in South Korea to not get in touch with the esport scene as a starcraft player while in foreigner lands the "I just play the campaign and everything else is nonextistent for me"-attitude is a quite common thing) there would be more of them.
But the difference is: as a somewhat talented player somewhere in the nonkorean regions you will probably get some success because there are only very few players as good as you from your region. It's somewhat realistic to not get stomped everytime you get on a slightly bigger stage. You can take one step after another. And somewhere at the top you might be confronted with an unclimbable hurdle - but probably not until the Ro4 of a big tournament.
Meanwhile in South Korea you'll already get stomped in the qualifiers for the only relevant tournament there is: GSL. How many of those somewhat talented players will be deterred from persevering until they break the wall because of the unbelievable superior 8 to 16 talents on the top of the SC2-olymp? Only the really stubborn guys who'll end up as those somewhat talented players and the real great talents will make it through this wall.
This would mean that the trying playerbase had to be much bigger than the 32 to 50 actual and almost GSL-players we have in South Korea seems to indicate. If we say that we have 10 talents of the calibre of Serral or almost Serral (considering ups and downs) in South Korea this would mean that we have to assume a seriously trying playerbase 10 times bigger in South Korea than in the rest of the world - IF talent is a bigger factor than we assumed so far, that is.
