When K9 is casting I tend to turn of my stream sound no mater how much I like day9 I just can't stand Husky. Kaelaris+ Apollo is a casting duo I like and ofcourse Tastosis but then again it's hard to not like Tastosis, and Bitterdam is also a decent casting duo.
And sorry to say but you're not the best player in the world if you can't handle cheeses. If you wanna be the greatest you can handle cheese and also throw in some cheese time to time, that's why I am still think that Mvp is the greatest player in the world. SC2 is about mind games, mechanics and builds not just mechanics and builds. While Innovation is probably the best with the mechanics and builds he just lacks a lil bit too much in the mind games department to be called the best SC2 player in the world.
And while I dislike cheese and prefer macro games when it games to playing or watching I did enjoy the upset by Maru. Keep in mind they're pro's they're earning money with it so if you know a way to beat your opponent you go for that cause you want that money. And cheesing is part of RTS since the beginning of it's genre and most of the time easy to deal with.
