ESL Pro Tour qualifiers are a ghost town and has a double elim bracket to give foreigners extra chances compared to WCS single elim: Even with the format being more forgiving, EPT qualifiers are still easier than ever and the group stage is mostly(IMO) a formality before things begin.
Neeb finishing 4th in a group with 2 foreigners. Clem, the EU champion, 3-0ed by GSL runner up (in the groups!): We don't even need to bring Maru and Byun into this,this goes beyond "upset" territory(upset would be Serral making it close or Reynor getting 3rd) this is just getting outclassed.
Region lock removed: Even people who faithfully preached the"faceless foreigners are ruining starcraft" dogma think its ok to end region lock.
International tournament winrate: Foreigners have won Blizzcon and GSL vs the World, but they're getting outperformed by Koreans overall, losing every single weekender non-season finals tournament. The Maru/Korean terran finals is no longer only a GSL issue.
I could go on with this for ages, there's plenty to be said about it but i think the most notable facts that concern this discussion are here.
