I totally agree with this.
Right now I've been training my prospecting level and weaponsmithing level together, but I have to go back to questing now because I'm out of cash so I can't buy the flux to make bars anymore..
It will probably get better with the addition of an Auction House or something like that, because we would be able to sell bars/crafted items but right now it's not very appealing to train gathering/crafting. Gathering is supposed to give you profit!
Therefore I think it would be nice if the price of the items needed for crafting (the flux etc.) would be lowered a little more.
