Following the way of similar question for the Monk and the Barbarian, I'd like to ask the same question for the Demon Hunter.

I know that there's a similar question, but its focus was Nightmare difficulty and none of the answers addressed Inferno.

Now to the question: for a Demon Hunter, high DPS should come natural through a correct itemization. At the moment (I'm still in Nightmare), I'm focusing on damage-increasing skills, since a high-dps grants me an easy dispatch of my enemies, without having to worry of being touched. Is this the main focus even at higher difficulties? Or should I switch to health restoring abilities (as Elemental Arrow with Nether Tentacles, or Marked for Death with Death Toll, or Shadow Power), to balance the higher lethality of the monsters?

Example builds, with explanation of the choices, would be greatly appreciated.
