I just recently realized that the 3 base craft schools: Blacksmith, Scholar, and Outfitter no longer support eachother like they seemed to be intitially designed to do. I think it was broken from the Scholar revamp.
Originally they were linked as such:
Blacksmith -> shared Stoneworking with -> Scholar
Scholar -> shared Clothworking with -> Outfitter
Outfitter -> shared Metalworking with -> Blacksmith
The three schools had one skill in common with one another that could be used to support leveling the others, but it seems that Scholar lost clothworking thus severing the link between Scholar and Outfitter and ultimately making Blacksmith the only true base class currently.
