Some of the future content seems promising. However, most of the other crafting professions do not have enough unique max skill level items to craft that compare to PvP gear.
If the expertise stats from PVP gear would be on a mod/armor/enhancement slot and allow players to remove it and place it into crafted gear, there would be a reason to sell orange crafted gear at end game.
Why does everyone have to always bring up PvP when he is clearly talking about End Game PvE. Whats wrong with you PvP obsessed people? Also if what you are talking about were to happen would that make every pvper automatically pick whatever craft was capable of doing that so that they wouldn't be forced to be slaved to the market? Only way that works is if mutiple crafting professions had access to this ability and if that is what you wanted to say you left it out of your post.
