Game changer ranger items

[RipVanFish]

Insofar as a ranger can be effective, what are the best items to (realistically) get them? A guide recommended paying attention to their survivability as well as their dps, so outside of dragon loot what is the best way to kit one out?

I have an fbss, dual EBWs and a gigantic zweihander on mine, not sure whether to emphasize strength gear, ac/hp gear, or some combination of the two for his armor slots though.
