Let's go back to 2012. What if we had a zerg in the same class as a 2018 Serral? (Stephano was not at that level). Back then there were lots of complaints about how Koreans were winning every international tournament and how they were "boring".
Now we look at recent years. According to one of my friends, viewership of SC2 had dropped ever since Serral started to dominate the scene which turned off lots of Korean viewers who want to see their domestic players win.
Now I'm not qualified to discuss the specifics of these issues so if someone who's more educated on this kind of topic can chime in then that would be great!
