Crafting and City associations

I was thinking for a idea to essentially create associations to choices early in the game to determine key elements to crafting.

Players would be from one certain 'home_city', but would then have to choose a second city to become a tradesman. So in a way those two things could define the way the player would relate to crafting and professions.

For example, a player could be from a city that is a miner city, but he chose to become a tradesman in another city.

Basically it would just put a bonus to certain professions to you depending on which choices you make very early in the game.

But the result would be multiplicative to the choices that you make at that stage of the game.

I don't know, what do you think?
