Balance between Control and Craftsmanship?

[Jet]

Control > Craftsmenship

1. Control helps with atherial sparking and elemental destablization
2. Control helps with recovering from elemental destablization
3. Only certain recipes will benefit from Craftsmenship
4. All recipes will benefit from + Control

That's not the whole story.

Craftsmanship/Magic Craftsmanship raise the chances of successful synth attempts, as well as raise the values of quality and progress that you get on each successful synth. As Technolust said, certain recipes benefit from craftsmanship (and the rest from magic craftsmanship), but it's not currently known if recipes get full benefit from one and none from the other, or if recipes simply lean on one or the other.

Also, raising certain element stats are said to help stabilize related recipes. This would theoretically benefit the synth in the same way control would.

To give you practical (if not obvious) advice, if you are going unstable/sparking during your synths, raise your control. If you're doing fine with stability, try to raise your (magic/)craftsmanship, so that you can be more successful in each synth attempt.

Once you're a high ranking crafter, and attempting to make hq mats and gear of lower rank, you'll definitely want to go craftsmanship over control, since you won't have a control problem for recipes so far below your rank.

Hope that rounds out your crafting a bit more. Cheers.
