What needs to be fixed in the Tribes of the East in patch 3.1?

Yeah, there's definitely a lack of spells... not just in Heroes 3, but also in Heroes 4, where there were some interesting spells, like "Dragon Strength," which could be used for summoning, "Fire Aura," and "Fatigue" (even if it just reduced movement points by 2, or 3 for experts) and many others. And for exploration, "Vision" and "Scout" are great.
