For artisans in Everquest 2, the dependency on other classes is both obnoxious and impeding to your personal growth as a businessman. The worst part of crafting in my opinion is the constant need for other crafters to make the parts you cant, and to take advantage of the dependency by selling for ridiculously high prices.
Fortunately, EQ2 has left a bug in the scribing process: the ability to scribe volume 10 books regardless of class.
All you need to do is to find a Scholar/Craftsman/Outfitter to buy you their "essentials volume 10" and scribe it, and you?re done.
Then, you can lvl up to 19 in crafting without interdependency.
