It doesn't take much creativity to devise ways to limit the impact crafting can have on endgame while giving them a market. Give raiders material drops from their victories required for our high level crafts, which also gives them a way to fund their potential purchase. Gate our acquisition rate of some unsaleable materials to help avoid RMT and prevent market flooding. If materia is too much of an issue the final craft could be devoid of slots, like very low level gear. Even with all those barriers it should not be the best the game has to offer, but if they turned out as ilvl 190nq 195hq. I think that would be pretty well balanced. Similar time/effort to get as eso gear, while being slightly less desirable and unable to upgrade to ilvl210.
