I say get rid of the "adorning" skill after splitting it from the breaking down because you can eliminate an entire pseudotradeskill that often performs frustrating combines that offer zero skillups and zero experience.
Adorning as a separate tradeskill is superfluous anyway. If I can make swords, I also know how to embed a jewel into the hilt. If I can make clothing, I also know how to make gold tassles. If I can make armor, I also know how to etch lettering into it. And on and on.
People worry about a glut of components if transmuting were a simple breakdown skill like harvesting. Well then you could figure a way to use them as or combine them into tradeskill rares. This is not nonsensical...after all, how does one take a rare plus scrap material, create a mastercrafted item, then be able to transmute it? The process is surely reversible in a manner of speaking.
