Description of your suggestion.

Why not make it more less arbitrary for the rareness of crafts and make it linked with the leveling system
Less tedious and more fun
I absolutely loved the mod but the absolute randomness is so annoying

First of all, the tiering of items is not completely random, as higher rarities have a smaller chance to get applied.
TieredZ has already a compat with LevelZ. The smither skill increases the chance to get higher rarities.
