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

After the release of Tribes of the East, there is a noticeable lack of a reptile race (like in the 3rd part). In Heroes 5, each race has its own type of territory where they fight better. In Tribes of the East, two new types of territory appeared – swamp and one for the orcs (I don't remember what it's called). So, it turns out that a race for the swamp is missing! This raises the question of why the swamp was even created if it's not really used. Therefore, I would like to add a new reptile race and even create a campaign for them. The plot of the campaign is a war with the Barbarians (similar to the campaign from Heroes 3: The Restoration of Erathia), where in the final mission, we have an alternative choice to side with one or the other (i.e., we can become traitors). Also, I would like to replace the cyclops model with a monster model! Move the cyclops to the 6th level instead of the wyvern (the wyvern just doesn't fit with the Barbarians!), and send the wyvern to the reptile race.
