Step One: As a previous user said, I would make the crystals drop in dunjins, rather than fates, queing as a low level DPS is painful and no one uses the HW fates to level.

Step Two: Keep as is, it was kinda nice doing dunjins like Snow Cloak again. I also forgot how cool the Vault was.

Step Three: I would keep it similar to the current system in grinding out items, except I would ease up on the number a little bit (IE: instead of 800 Alex runs, make it closer to 600 cause I'm a masochist)
HOWEVER I would also add a crafting token system. Don't want to run content? Would rather craft or trade? Then I would want a system where you turn in a bunch of HQ crafts for the same items, to give players a choice between one raiding, crafting, or both.
