What should be added to the top five from the previous installments?

Independent heroes and an independent army! In Heroes 4, there were a lot of heroes to choose from, but they were all generic. In Heroes 5, on the other hand, each hero is unique. We need MANY INDIVIDUAL heroes with distinct personalities. And a second class (of hero) for each castle. For example, a Knight and a Priest, a Necromancer and a Death Knight – that is, in each castle, one hero is designed for magic, and the other for melee combat.
P.S. All of this was in Heroes 4 (these were my first Heroes), and probably in previous posts. Just a reminder.)
