Crafting is more or less useless.
Pre cap, every item you need is from dungeons/quest rewards. Post cap, tome/dungeons. And items that could be good inbetween sets cost 70k+ each.
Any item worthwhile in a dungeon is untradable, so there is no reason to buy any gear.

The gear in dungeons is mostly undyeable... Meaning the market for that is limited, and everyone ends up the same.
Crafting and gathering needs to be a viable alternative by far... The hardest to make sets need to completely rival that what dungeons offer, allowing people alternative means to get gear other than farming.... Allowing customisation end game.
But remember, regardless of what happens, bots will always control the markets... They will always flood markets with large amounts of HQ items for cheaper as they can afford to. They can afford to create artificial demand for items, and they will harm the economy in more ways than one.

If crafting become useful, they need to be looked at thoroughly.
