I think we have two seperate versions of the Vengeance DH here. One was built on the self healing model, to be comparable to DKs, while the other was built on the idea of torturing your targets to weaken their attacks against you. There was some hint that Fury was unique to Havoc (during the panel talking about Havoc: "these guys have their own custom resource: Fury"), so Pain may simply be the resource for Vengeance. We inflict Pain with our fire spells, and spend Pain to make our opponents do less damage to us (or our allies) with disruptive debuffs. That sounds like a solid theme for a lightly armored, fel magic, tanking spec. The problem is that they hadn't nailed down the vision on that tightly enough to present it well. My theory being, because they had prepared for Blizzcon with the scrapped self-healing model that we see in the Demo and had to switch directions shortly before.
