Silius posted on the official forum that they have !@#$%^&* the way you obtain crafting recipes. You no longer have to grind on gray work orders to obtain the recipes you need. You can read the post here.
Ok so here is a follow up with more details then what I have posted previously and stated in game.
Recipes no longer drop from work orders they are gained by cashing in silver and gold masterwork sigils that drop in place of recipes. Based on the tier of your character and the tier of the recipe you want to learn their is a certain number of silver sigils required plus a monetary fee (in the form of buying a component). In order to receive the training you want.
The rules about getting sigils are the same as the old rules for getting recipes and rarely you will get gold sigils which you can exchange for any recipe (basically 1 gold sigil is worth the value of several silver sigils). Why did I make this change? Because players having to grind grey work orders to get what they felt they were entitled to was never the intent. That is what this change is meant to address but as a side benefit I removed one layer of luck rolls since you can now choose which recipe you want first.
Hopefully this change makes you all a little bit happier in that you do not have to grind greys or worry about getting a recipe you do not want or may already have.
