What would you change in Heroes of Might and Magic IV?

The logic is simple: since Heroes of Might and Magic V was released, it means that Heroes of Might and Magic IV has been immortalized in its original form!!!

But that's not necessarily true! Heroes of Might and Magic III is still being updated... or rather, Heroes of Might and Magic III½. They are planning to release version 3.59 soon... so everything changes ;)
