You know how you actually start each game hunting down the bushes wild silkweet and the little flowers to get good resources. How you can see the complete map . would it not be better to have an actually fog of war and a scout class. he/she removes the fog of war , looks for hidden buildings, and brings back plants he find on his searches. now that the wood cost for ladders is gone he schould be able to build ladders bij himself to go up or down a level or just make it an innate ability of the class. As tool to make him a walking stick made at the carpenter
The hidden building part could add quest to the map
or just needed to find those pesky goblins.
he could spot animals for the herder
he could spot minerals in the rocks
