Some day it would be a wonderful thing to add player buildable imperial training centers. these centers would have some of the adventurer trainers and all the approprate crafting trainers. I would think that these structures would be placed by the imperial forces near settlements that have recources near them so if its a major town and it had metal and cloth near it then they would have the approprate trainers for those skills. Islands like saritova any of the major guild islands would be probably be the choice locations in other words lets creat some hubs of activity thru out the world
