So I finally dived into Blacksmithing last night and came to a pretty obvious realization. Flawless Synthesis is fantastic to use to get through the first 10 levels of a craft! You one and two shot pretty much anything up to level 15, and you don't even have to improve your tools or gear to keep up.

After I get Ingenuity I and a good number of leves back, I'm either going to bounce back to Leatherworker or Weaver. The allure of Careful Synthesis II is just too strong
