Shouldn't the order of training follow that which, in real life, is harder to produce by the methods the game possesses? I dislike the "let's follow a pre-historic" order, PlaneShift has the technology to produce steel and it's obviously something shared by all the smiths (read: common knowledge), so it makes little sense to make each individual go through a historical order just for the sake of it. Unless it would be a smith tradition, that would make it more acceptable, I guess.
For now it is true that only steel is used, but that is because the only "industry" we have is weapon and shield making, war things. Unless somehow steel stock becomes the cheapest metal, which it shouldn't, other metals will eventually be used just because they're cheaper. Money is currently hugely wrong, as is the economy in general, everyone is ridiculously rich these days by setting standards (how many of us couldn't afford a healthy, well trained pterosaur? Most of us has enough for a small squad of them, though law would keep us from that). Fixing the economy to become something realistic will take a long time, but my point is: don't make them force us to use all the materials just because the current economy deems it useless. When the economy is fixed and most people won't be able to afford steel weapons as if they're bread, all the other materials will, likely, be used.
