Ok, I dont know if this has been put down before and I know I'm taking it directly from another game (I don't actually play WoW, just watched a friend play it.) But it's just an idea I'm throwing out the masses.
I think that being able to choose a craft would add a whole new dimension to FL. Like weapon craft, armor craft, potion making, stave craft perhaps. I dont know how this would balance out, but I think it would be cool if you could select one craft at a certain level and then be able to make better things as your proficiency/level increases. You would obviously need to find items that would be prerequisites to the the items you can make, and maybe even need special tools and be in a certain place (like a forge) to make them. Perhaps some of the prerequisite items would even be rare and such to make them harder to find.
So how does it go down?
