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

In Heroes 4, the editor is the best, and the game's overall seriousness is incomparable to Heroes 3 and 5. But I would like to have random scrolls in the editor. The game should have more artwork, and items should be craftable. There should be 10 times more heroes and creatures. And more blood and gore! And most importantly, it should be possible to record demos, naturally in a small size using a built-in program, rather than recording a movie from the screen.
