I have several thousand Artisan’s Mettle left over from Dragonflight, with nothing really to spend them on. It would be nice if we had a way to convert all that leftover mettle to the new Artisan’s Acuity… even at a significant loss.
…Considering the weekly stipend of 150 mettle is still there, no.
That, and there’s already a (really expensive) method of getting tons of acuity: cycling through all the professions every Tuesday afternoon/Friday night to complete patron orders for acuity.
