Yes, it seems to be the popular trend. Of course, as you can see, I'm just starting out, so Auction House is not exactly for me yet, but I figure that once I hit late Nightmare or #$&*@!, that's probably going to be my course of action, although I'm not familiar with how it's going to be with gold/dollars in it, like, will a bid in dollars always cover one in gold? Is there an exchange rate? Does the seller choose, gold only, money only, or either? Stuff like this.
So far, the Demon Hunter seems like a big Glass Cannon. Also, I'm a bit disappointed in dual-wielding, it's almost exclusively better to simply pack a quiver, even with a hand crossbow (God knows why this even work), since every quiver I've seen so far has attack speed + 10%, which not only is huge (seriously, what kind of bonus is this for a 6th-level character?), but more than makes up for the 15% speed augment in dual-wielding, plus your second handcrossbow might suck, or not be quite on par with the main, and it does not actually add up the stats, it attacks separately (which makes sense, of course).
