At least in MoP jewelcrafters could make the Voltron panthers. Though yes, I’d happily go back to the days when a piece of gear could have multiple gem slots.
My enchanter misses being able to enchant just about every gear slot. And being able to combine dust into crystals. Dear lord, I’d give a lot to be able to combine dust into crystals rather than throw yet another toon onto the mythic+ treadmill just to get purples to DE.
