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

But there are many abilities. (I don't remember their abilities, health points). For example: Angel abilities: resurrecting an ally, flying. Health - 240 points. Damage - 30 points. Defense - 40 points.
Archangel abilities: flying, resurrecting an ally, resistance to chaos and death magic, large shield. Health - 280 points. Damage - 33 points. Defense - 50 points.
Understood, Zybr.:smile02:

There are quite enough abilities; overabundance is also bad.
For example, consider angels. Building one costs more than 30k gold and a lot of resources. Upgrading will cost another 15k + resources. Where will we get these funds? Should we give up on potions and heroes? Drag out the game? And what if the opponent decides not to delay and meets us while we're running around with nothing? :)
Okay, let's say we upgraded the angels. But what about further upgrades? And if there's no Town Portal? Will we have to spend at least 3-4 days traveling home? In the 4th game, you can't create a chain like in the 3rd or 5th for instant transfer, upgrade, and return, because creatures have their own movement range. As a result, we'll just get bogged down with this upgrade, fall behind in development, and ultimately lose.
