I'm all for the more... powerleveler folk... being the blacksmiths. If you don't have lots of time to spend idly pounding the anvil, be a metallurgist, or a miner, or whatever new profession comes along. We don't need more users of material, we need more suppliers of it.
But Harnquist tells you, 'Oh-ho, I have to charge you for training now, because you're on track to be my competitor here!'
That means he crafts stuff.
And if he trains you, that means he knows more than you do. So... Harn/Tras need to sell better stuff, I guess.
