For example, say you are making a helm you have to cut out a pattern on a sheet of metal(which you could maybe buy, or smelt yourself) with some shears, dish it out with a dishing hammer on a stump, then punch holes and rivet a face plate or nasal of what have you with a ball peen. For things like pauldrons you should have to cut out all of the lames and rivet them together correctly.
Alls I'm saying is smithing should have more to it than making armor from a menu or with a progress bar then its done. It should be a dynamic, intuitive process that takes a while and is at least semi realistic. I don't expect it to be exactly the same as the real thing, but hopefully a step closer to that.
