I'm not sure if this has been discussed before, but I'd like to suggest something. Sometimes, the resources in the starting area are depleted by buildings with Seers, which search for a specific artifact and offer a reward for completing quests. Why not make it so that you can know the reward for a specific quest in advance? This would provide more incentive to search for the required artifacts. Often, by the time you find the right artifact and bring it, the reward seems insignificant, like 5k experience or gold. You could also tie this to, for example, the "Scout" skill. That is, a hero with a high "Scout" skill could know what the reward is, thereby increasing the value of this otherwise useless skill.
