Make it difficult to obtain (I am not saying statistically impossible, mind you), but also make the content grant tangential rewards that, on their own, justify the time and energy expenditure on said content. Do this through organic planning that goes beyond the current level cap for the game, so that you don't find yourself constantly superseding items that were granted in past content. Or if you can't totally do this, at least keep revising the stats of the old gear, so that it never loses its viability in game.
