From what I've read, I'll bet anything that Discipline regeneration is the key issue - survival in Inferno seems to rely primarily on defence, and from what I've read of the classes, Discipline regenerates slower than every other resource in the game. If the thing most necessary to survival is the rarest resource, then survival would probably be difficult. Either 1) Discipline regenerates too slowly/Discipline costs are too high, 2) DHs need to gear even more defence than other classes, 3) some kind of skill combo which makes them much more viable simply hasn't been discovered yet or 4) Blizzard really didn't test this class in Inferno all that much and thinks they're much better/more balanced than is actually the case.
