I'd like to see a normalized progression between the types of metal. I've been spamming only steel plates on this tin can build, because you can simply stack more than the other metals, ending up as the universal best. Metal types already have tradeoffs built into them, why also make tungsten harder to craft?
If everything ended up at 112% at the same pace, I think it wouldn't destroy certain types of crafting as much. But it's possible anything that has optional components that add a percent of requirements also get extra screwed, which might be fine for Energy Shields but not for Metal Armors
