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

5). We need to ask Dalai if they can add new classes.

They changed classes for heroes, so they know how it's done. Moreover, there's an example of a "three-skill" class – the Archmage. In general, I'd like to see some interesting class solutions, for example, a mix of Lord with something to create a kind of "economic" class.

In the latest version, Equips don't disappear.

What is considered the latest version? I was talking about 3.51 – they seem to disappear there.
