Since the expansion first came out we heard people complaining about having to farm rep to obtain valor gear. As someone who started raiding the second week the raids were out I only ever had to buy one piece of valor gear. I received all the pieces I needed from raiding. If you're raiding then for the most part you're going to get all your gear in the raid and won't need valor gear. And if you're not raiding then you don't need the gear to begin with.
