Update with the release of Destiny of Velious: Gaining tradeskill experience has changed. First time creation and first time pristine creation bonuses have been removed. Instead tradeskill quests, including writs, give much more experience than they previously did. This was done in an effort to balance tradeskill classes between each other so that classes with fewer recipes weren't taking a longer time to level just because they weren't able to take advantage of the first time bonuses that other classes had access to. If you do quests, you should find that you level up just as fast, if not faster than you did by making one of each recipe.
