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

In the fourth installment of Heroes, almost everything suits me. What I don't like are the statistics of some creatures. For example, the Monster. For its type, it's very weak. Champion – champion of what? It's the weakest of the fourth-level creatures. If a Vampire had 100 hit points instead of 75, it would easily defeat the Champion. What is a Catapult? It's some kind of machine that's stronger than a Hydra, and even the Champion. An Angel should be strong, but it's just… weak. The name "Devil" suggests that it's death for any creature. But that's far from the truth. A Mantis easily defeats a Devil, even though the Devil summons Ice Demons. What is a Phoenix doing in Nature? In my opinion, it should belong to Chaos, and the Hydra should be in Nature. I could complain for a long time about the creatures in the fourth Heroes game. But there's one more thing. It's hard to express it right away. For now, think about what you would change in the creatures.
