Sounds like you are racist against Korean video game developers, and you need an invisible hand to blame for the failure of ArenaNet.
Koreans have nothing to do with this. Nexon has nothing to do with this. ArenaNet just realized the perfection of the Korean MMORPG model, and Guild Wars 2 is what happens when clueless American MMORPG developers try to emulate superior Korean MMORPG games. It ends badly.
