Cyclopes are okay, they'll do, but the monsters' damage is too high, it needs to be reduced! Let them have more initiative, but reduce the damage, at least to 80, it's already a monster! And regarding Heaven - since they are almost a copy, does that mean we should take everything from Heroes 3? No, because a large group of fans of Heroes 5 will go to Nival with a protest and accuse them of talentless copying due to a lack of imagination!:(

Don't get too carried away. :)
Here is my answer to Imp. Specifically, you'll ruin the balance, and it will be a pain to play against such monsters! And the creatures are almost an exact copy of Heroes 3. It's silly - Ogres have had their time, Hobgoblins have no place in the game, more imagination is needed!
On the other hand, the development of technology increasingly gives rise to remakes of old hits, made in accordance with modern standards. For example, remember Morrowind, which was more of a remake of Daggerfall than its sequel. Return to Castle Wolfenstein, Warcraft 3 - old ideas, adapted to a new style. Not clones, but great games of the past, the potential of which makes people constantly return to them, re-examining what was created before.
Please, offer your ideas.
