You make a good point about drybrushing. The only thing I use it for is groundwork on bases. I'm not one of those people who scoff at it as a short cut (I like short cuts), I don't do it because it so damn difficult to get good results that way. I don't have the skill to make it look good (it always looks hellishly messy when done by me), so for me it is no short cut at all. Regular painting is much easier to my mind.
Just my thought on the matter.
