Amineri's post is one of the reasons I'd like to see more information across the board.
One of the biggest problems in FFXIV's economy is overabundance. Certain things are just way too readily available. Which is why I am not necessarily against the negation of nuggets. Making bronze nuggets you get 12 in a batch, 2 of those can be used to create 32 nails.
Basically a stack of bronze nuggets makes 15 stacks of nails. There is not one recipe that uses more than 1 "nails." This means nails are basically worthless. They aren't ideal to make for skill because you will end up with just ridiculous amounts that you can't sell and they aren't ideal to sell because they are so worthless. To add further issues to this there are 6 different types of nails.
This is a prime example of where streamlining needs to take place... But I still don't think the answer is to go from needing nails in their current form to just having recipes that used to require nails now require an ingot. There is plenty of room for adjustment in every stage of crafting nails that would streamline their use and give them greater relevance.
Let's work under the assumption that the new ingot recipe will yield one ingot. let's then have one ingot make 3-4 "Boxes of Nails." One box is the item. Any recipe that uses nails uses up the full "box."
Now instead of having one batch of ore turning into about 3 stacks of nails you have one batch of ore turning into 4 usable items. The value of nails goes up. Crafters realize they can grind on nails and keep them for further use or sell them and actually make money off of them.
