The very end game products are very rare noone wears them, but the second stage is not soo bad, you need to farm exaclty as it says to in nagrand primal airs drop the breath of winds, fire elemntals i killed alot of these in un'goro while farming the crystals, and core of earth is the easiest to come by kill the rock guys in nagrand, and you can mine them once they die.  its not hard at all DPS spec but if u do low damage plan to afk tank all day or get a guildie to help. :) its by far not a dead end new tanks need felsteel helm, chest, and other pieces to get rdy to tank for heroic instances. Also healadins will want khorium plate for healing, its got good stuff and i beleive they are also a blue item pretty sure you can sell it for what its worth. same with tanking gear isnt much better than those in low lvl instances alot of defense gear is obtained through quests. group quests, and instances.
