Additional Crafting License – expand this to unlock all 9 crafting disciplines. I know this won’t interest most, but it seems like a simple upgrade to the gem store that would immediately get another 5000 gems out of me at least. A long time ago I mastered all disciplines on my 1 main toon that I enjoy playing the most. I don’t really want to do it again on other toons and swapping disciplines at 50 silver a pop is tedious.
