agreed - i would also like to either "trade maps" or even have a spell that -massively- reaveals map - there is the eagle eye spell but it isent very good or powerfull - if it GAVE the bonus allways then it would be worth while.

agreed; exploration is currently the only reason i build ships. trade map info diplomatic option would at least give me a reason to use diplomacy other than to steal daughters.

i would also like it if diplomats were able to traverse enemy territory without incurring a transgression (it may work like this already; i'm not sure)

on a related note does anyone know what happened to the reveal spell?

It would actually make sense to populate out the harbor technology line; enabling map trading with other factions once you discover the tech, along with a food resource placement for fishes and such.
