This is an awesome idea... You mean, the young and new people need to learn something like blacksmithing, and thats their priority number one doing, which they do 30% faster than a non specialist?

That would be awesome and they could loose morale like 10% slower too because they are happier with their job. Man, but it would suck when you are still in the earlier stages because in the event that the village is attacked n a bad raid, if you don't defeat them right away and they kill a bunch of your specialist, if you relied on them greatly, it is going to hurt when winter comes.

This idea has legs. It would also add a level of personalisation to the inhabitants. At the moment, them having names is a bit redundant as they don't really offer any insight into their day to day lives. But if you lost xxx who was the village blacksmith, then i guarantee you would take more notice of xxx and his location, well-being, health status etc....
I hope this gets looked at in earnest. It also opens up possibilities in other specialised fields based on the current game economics and buildings.
