China having a really good showing. As someone who hasn't really been following the Chinese scene, it's cool to see they're at least competitive with the NA scene. Not to mention they were probably playing with lag.
Awesome to see PSiArc qualify even if he didn't have the best showing. Really great to see such an underrepresented region.
Lots of NA ladder heroes doing well, which is cool to see. Players like MCanning, Silky, Epic, ect.
Protoss surpasses Zerg as the most qualifying race for WCS (14 P 10 Z 8 T). Overall relatively even racial distribution, but given how Zerg dominated it's been in the past, it's cool to see it's being mixed up a bit.
