@Tuoni on the crafting Q&A it says that you can learn all recipes. Some of them are rare and harder to find, some will only be available on certain worlds, and others can only be learned through relics. So it sounds like there will be some difficulty in finding the highest tier recipes, and probably not worth it to those that want to focus on pvp unless they want a very specific item.

Recipes:
You can learn all crafting recipes. There are no specializations. No limits on the number of crafting professions you can have.
Some recipes can only be learned on specific planets.
Some recipes (and abilities) are learned through ancient knowledge and relics.
Some recipes will be rare, but no recipe will be limited to a set amount of players.
There are no special secret dev-controlled crafting recipes.
You cannot share your recipes. You can just give someone else a completed item to let them study it anyway.
