Muscle Memory is a weird one. It is only usable at the very start of a craft, and then only functions as a 60%-Off version of Piece by Piece.

I honestly cannot come up with a scenario I would prefer to use Muscle Memory over Piece by Piece. For that matter, I cannot come up with any situations where I would want to use Muscle Memory over Maker's Mark and Flawless Synthesis. But then, I do have all 8 crafts at 60 ...


TC, WVR 15, ALC 15, BSM 15, CUL 37, CRP 50, ALC 50, WVR 50, then the rest to 50 in whatever order you see fit. Try to bring them all up more or less evenly through the Heavensward levels though; not only is the under-the-level penalty a bit more harsh than in ARR, but there is a lot more inter-dependency among classes for refined materials. You'll want to be able to produce those refined materials, as it is much cheaper than going to the board for them. Not only that, but you will be able to share crafting gear (with the MH and OH tools excepted, of course) easier if they are all the same level.
