I thought of an entirely cosmetic suggestion which I think would nevertheless do some good for the game in the form of the smithing process.
In the real world, master smiths know tricks that the common smiths don't. I saw somewhere that some giant Japanese smith family dating back centuries is still cranking out masterwork katanas, which are bought by top-level executives for insane prices and hung on their wall in the corporate war office. I am sorry I don't remember the name, as this is something I saw in like the late 1990s, but I definitely remember the documentary. I know making a katana of that level involves all sorts of stuff to make the weapon perfectly balanced, as well as folding the steel tons of times to make it as hardy as possible. A little apprentice can't do that.
The Japanese smith heir is the Legendary smith, so he knows a lot of stuff that an apprentice or even an average smith doesn't. To reflect this in the game, why not make the TEXT of the apprentice something plain and humble, then the journeyman is a little fancier, until at Legendary the smithing text is REALLY something fancy.
Going a step further, different text for each forgeable item could be written up, with a different body of text for each smithing rank. So, an Apprentice makes a full-plate and gets certain text, Journeyman a bit better, and at Legendary it's smithing voodoo. Then, you go to hand axe, same progression. Etc.
It's not really something that'll use any in-game resources, and it WILL take some time by the staff, but I think it would add to the flavor of smithing quite a bit.
Thank you for reading my idea.
And you won't understand the cause of your grief...
...But you'll always follow the voices beneath.
To make this accurate and fully descriptive, I would need to do that research and get accurate information. Some of htis stuff, if @Tecton ends up not wanting in there, would be gone but these are examples of the type of stuff I'd be looking to put in there. Not what it would necessarily end up as, but that's some of the stuff I'd be looking to find.
