Sometimes advanced farming feels like a bit obsolete and you feel like it should make farming and other tasks easier itself since the skills affect is very minor. Maybe the skill could be tweaked and possibly get associated with some sort of Advanced engineering skill that would allow you to upgrade certain items so that they would be more useful. Like for example use tools and resources to add an extension to trading carts which would allow them to carry logs or to make primal lenses that could be used to make a telescope or to upgrade your map so you can make primal marks on it. The possibilities for this sort of "luxury" skill could really be useful and fun.
Also school's specility could be writing which would allow you to make signs that would have your text on them which would also be very useful and fun within the communities.
