The dichotomy between the promise of actual DoH classes and what they realistically bring to the table is ridiculous. The great irony is that crafting in a Final Fantasy game has never been more engaging - but at the same time never been so useless. Besides some very occasional Militia gear and pre-relics, the entirety of endgame crafting consists of making HQ gear for other crafters (quests and AF). 2 star gear is a curiosity at best for all the good reasons listed by posters before me. Guaranteed HQs will eventually make mincemeat out of the markets when the majority finally figures out that there is no difficulty difference besides pushing a few extra buttons. Already I see HQ/NQ selling about the same in some instances and even HQ less than NQ.
When 1.0 was released I was convinced that by making DoH clases, on par with DoW/M, meant that they would be privy to all the same privileges - quests, parties, gear, storyline, etc. The potential was absolutely enormous - and all we got was Hamlet Defense. Crafting will never be key to this game and that's the way Yoshi wants it. It is a sideshow only.
