Now it's telling me I can't make alloys of any kind with ingots. Only ore. I have iron ingots, and charcoal (hell I have corundum ingots for that matter), why can't I smelt steel with that? Ingots are even EASIER than ore to smelt. I mean you don't have to be a metallurgist to know that. It's just common sense.
And before someone goes prattling on about how it's stupid to look for real-life logic in a game about magic, the game is based/on in real-life. Everything about the game except the races and the magic is based in real life. And not being able to smelt ingots is stupid.
I can't see how it overbalances the game somehow.
