I actually do close to nothing with the drumsetup for tunes I make. I've just always been a drummer and beeing able to hook it up to ableton (it automatically sets the pads to the correct sound if you open a kit in live) is very nice...
For drumming DnB you'd have to be a pretty fast drummer, I'm not at that level yet.
Altough I could do a standard amen break for about Half a minute
