^ ^ I believe it was Monk who said what you don't play can be more important than what you do.
In the context of dance music production, your job should be focusing on making better LOOPS. In a way, dubstep is some of the most repetitive dance music, as the tempo and spaced-out nature of the rhythm allow what is essentially a loop to feel more like a "song". ie people are more content with a strong dubstep loop that doesn't change, and don't want too many unanticipated musical ideas thrown in there.
If we call dubstep tempo '140BPM', then often times the loop occurs over half a bar, one bar, two bars or four bars, maybe eight, doubtful 16. This means that at most 8 bars is all you need to convey what you need to convey. Hell, even ONE BAR is enough to smash it as tunes like Icicle - Xylophobia clearly display.
This is the one area where I think young producers get it 100% wrong when trying to make better beats. They look for problems in the way the tune evolves, rather than focusing on the depth of sound and the groove achieved between elements in the space of about 5 seconds! That's all the time you need to make an impact.
For example, take the tune TRG- Horny (reso's rmx)
His bassline loops every half-bar, meaning that the main bassline hook occurs twice for every kick-snare cycle. This adds a ton of dance floor momentum, and you're hooked in under TWO SECONDS.
