I played WoW shortly recently and it reminded me of something-recipes you can find out in the world.
It would add some variation to crafters, not having everyone know the same things, and would add a way people who don't craft can make gil (by selling recipes to crafters collecting them). I think it would be cool.
They could even have recipes drop in raids, perhaps. Maybe not the savage ones, but like, as an example, the recipe for 220 gear could drop in midas.
Of course, we should still have the majority of crafts just in the log like now, but having extra recipes for good stuff that you can find would add some incentive to do other content I think. Just a thought I had.
