I hadn't played much of the Demon Hunter in Diablo III since the good old M6 days (when the Marauder's set was incredibly strong, for those who didn't get a chance to try it), but the Unhallowed Essence set brought me right back to the class. The ability to put out a whole lot damage, punish enemies for being both high AND low health, all while filling the screen with rockets and fire was far too good to pass up. If you want to know what it takes to get started with this build, the video below will give you all your heart desires (*unless you desire more than a Diablo III guide...you're on your own there.)

If you just want a quick overview of the skills used, you can check that out right here.
