I wish fucking EVERYTHING didn't require basic mats. "Oh cool I can make starmetal tools, oh it's like 50 iron per starmetal bar and I need 50 bars for a full set of tools". It's not necessarily hard to get that much iron, but it is a bit annoying and just make prices very bottom heavy (iron ore is like .80g each on my server, starmetal ore is .15g). This is kind of helped later on with reagents since you can basically guarantee steel bars x2, except...
I wish it was easier to target farm reagents rather than just making money and buying them. I'm working on furnishing now and the amount of sandpaper (and to a lesser extent flux) I'm using is frankly disgusting.
