We do not expect any significant changes at 70**** crafting tier that would be worth another analysis post.
We designed Crafting Solver to be stable through the entire lifetime of Stormblood expansion.
For 70*** recipes, +10 CP equals roughly +25.3 Control or +39.4 Craftsmanship.
The stat distribution is approximately the same for all recipes at level 70.
We recommend melding as much CP as possible, with Control coming second in priority, and Craftsmanship third.
If you use Maker’s Mark with the Crafting Solver, you can safely leave Craftsmanship at minimum recipe requirement because it has no impact on Maker’s Mark.
