That's a much larger complaint about the overall design of the game, and it not aligning with how it was advertised. Currently, there is one best set of gear for PvE. Everything else you use is either stepping stones to help you get that gear, or sub-optimal, unless you're using it for PvP. It just seems a little misplaced to get upset that you can't buy that other set of suboptimal gear you want, instead of being upset that there is only one set of gear that you can use if you don't want to gimp yourself.
