Something really needs to be done about the transmutation formulas. As they are currently they are pretty silly. What alchemist is going to take 10 bronze bars (and a tainted orb) just to make 1 iron bar? That is at optimum. What other craft can take 30c worth of materials (just the bars, not sure what tainted orbs sell for at the pawn broker) and make something worth 6c?
I think either the amount of resources needed should drop drastically, or perhaps the output should skip a tier (bronze to make steel or gold, iron to make cobalt, steel to make mithril, etc) then it might be useful. At least make the value of the product more in line with the value of the ingredients.
