I love me some Wub. I really do. I play synthesizers so I'm probably a little biased. But what I love more than the Wub, is the hate for dubstep/brostep/nu-house whatever the cool kids are calling it these days.
Remember all the rock bands you've seen live? You can't tell me there havent been any guitarist with a tone that made your ears bleed. I love high-end dubstep productions for the sounds. The skill is maybe not directly visible, but definitely in the production (and I don't even mean songwriting) aspect of the song.
Next we have songwriting. Most dubstep I hear, is just as bland as every punk/rock/metal/-core band out there. Basic songwriting mechanics, often used on a mediocre level. Differend sounds? Oh no! Pinch harmonics, palm-muting, guitar effects? Same deal.
And what's with all the remixes right? Or should I say covers? Because that's basicly what they are. Many bands do their own thing with existing songs, often for worse if I'm to believe the internet.
As for performance. What's a fairly prominent trend with bands these days? Backing tracks. Dang, there goes spontaneity out the window. As for skill, I believe only the drummers have the backing tracks on monitors mostly, though I'm not sure about bands that use in-ear monitoring.
As for performance when it comes to Dubstep: Many artists will use effects real time, and still have to trigger all of their samples. THey also have somewhat of an Master of Ceremony task, meaning they have to hype the crowd up. Stage presence is still an important factor.
IN CONCLUSION
There's just an incredible amount of parallels between "live performance music" and the so called "dubstep" genre. Parallels that go beyond "collection of organised sound" or whatever.
And if you wanny try getting into the hype because that's how you roll, try looking at it like that. Worked for me.
Peace out homies.
