Which classes to focus for Desynthesis?

[AttacKat]

The Goal of Desynthesis is essentially to obtain rare/expensive Primal Demimateria from Primal Weapons in order to craft upgraded glowy versions of those weapons (i95) which will also be expensive.

Long story short. Gil/Vanity.

I guess we are on different paths. I am eyeing all the iL75 tools. Most expensive doesn't always translate to most profitable.
