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

This whole division thing is getting confusing. On the one hand, the other four races are logically opposed to each other in terms of morality, as well as in terms of name, units, and magic, but "Nature vs. Might" doesn't have that – they don't really spoil each other's morality, the names aren't antonyms, the units in both are wild, free creatures, and as for magic – Barbarians don't have much, but in general they rely on resistance, damage, a large number of hit points, and the size of their troops, while Nature gets all of that from magic, so you could even assume that Nature and Might are allies. But on the other hand, Nature symbolizes harmony and tranquility, while Might represents war, plunder, and discord. In my opinion, if Death is actually divided into undead and demons, then demons would be opposed to Nature, as they are unnatural and enraged creatures, and therefore perfectly suited to be Nature's main enemy.
