Let's just let this thread die. OP has only 3 posts and clearly just wants FFXIV to be more like FFXI when the two games shouldn't be compared.
And to answer the person above me.
Why? How would this improve or make the Crafting System better than what it is, besides replacing the interesting part of crafting with pure RNG? Your proposed system would just default to people using Google or a recipe-dedicated website to search what items a recipe needs, which makes hiding the recipe obsolete. It sounds neat in a single player game but not in an MMO for this day and age.
