Problems with Heroes of Might and Magic IV.

Try using that unit, it's like a Barbarian of level 20. And a hero on a horse is just a spectator, who doesn't really participate. He just casts a spell and immediately hides.
There is development. With the hero's participation on the battlefield, the gameplay becomes more interesting in terms of tactics.

Optimal, people just don't understand that version 4 has advanced the gameplay to a qualitatively new level. But I'm not going to claim which version is better or worse. And their reasoning boils down to something like this: I always played the first game. And then they made a second one, and I was horrified to see that there was a market. And why does a goat need an accordion if I don't know how to play it? In other words, I was doing great without a market in the first game, and now they're asking me to rack my brains with exchanging minerals. Ugh, they ruined the game.
