I already have all of the construction schools at 100 so the new change doesn't effect me, but I can see how this change could be annoying to some people. Especially people that don't own a plot to work on. So after thinking about it for a while, I had the following idea: Have the trainers for the various construction schools give out level appropriate quests to make a bunch of construction materials "for the empire" and have some coin/xp as a quest reward. That way people without plots can still level the construction schools and make some money while doing it.
