forum search is awful, and this is the closest result i found.

i agree, at least 2 bronze bar instead of 1 would be nice.
considering we need to put 3 bars in, it's mad we only get 1 bar out instead of 3.

take the weight too:
copper, 12
double for 24
tin, 8
combining to a weight of 32
bronze, 12

edit hold on...
bronze weapons and armour need 8 bars to craft.
armor 5, pick 10.
but... that's 1/3 of the starting resource?
so it's actually 24 bars, 15 bars, or 30 bars?

iron stuff needs 20...
