Sorry for the untimely answer, I've been rather swarmed with tasks these days. I think that it would most certainly be interesting to see TE upset EDG because they definitely stand a chance. It'll also make for good exposure to lesser-known yet just-as capable Chinese teams such as Trace Esports. However, I don't think it'll be ideal for the Madrid tournament. While I believe that EDG can stand a good chance against one of the other international teams regardless of their form (experience speaks tons and they aren't even that bad right now), I disagree if TE is in the picture. Sure, they're good, but they've probably never experienced a thrashing from an EMEA or a NA team.
For Madrid, I think it'll be better for the experienced EDG/FPX to make an attempt at getting top 4 instead of having a team with absolutely zero international experience despite being good try to take a map off Fnatic or some other great team and lose. The better Chinese teams do this tournament, the more attention it'll bring to the scene for the rest of the year.
But like Brian said, FengF would be very cool to watch on the international stage.
