I know this one's going to cause a rukus.
It's becoming more and more obvious to me that the biggest problem with making dwarven hammers unique is that the first person to research construction 8 gets both unique hammers and a much bigger advantage than in vanilla; where it was already a huge advantage.
Is it possible to move the Hammer of the Forge Lord to construction 10?
That way, as I understand it, it could be wished for but not forged.
