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

дибильную

Maybe it's worth choosing words more carefully? IMHO, but decency should be observed.

During battle, GO WITH A SWORD IN YOUR HANDS.

That's how heroes usually act. Well, they are also commanders, leaders – they don't just wave their weapons around.

And zombies with their arms outstretched forward.

This also happens in some movies. It's quite explainable, actually – the urge for living flesh. The only thing that doesn't look right with zombies is their flabby appearance and increased health.

4 LEVELS OF CREATURES

Why have 7 levels of creatures? Just because there's more room for imagination? I'd like to hear at least one sensible argument...

There are no upgrades in the first one. We'll forgive that, it's the first one. BUT IN THE 4TH???

What are upgrades for? Just because it's popular? Even without them, there are plenty of ways to invest money in the 4th game.
And alt-upgrades... IMHO, when there's nothing else to come up with for tactical maneuvers, they introduced alt-upgrades. Or for whiners who like to admire every little detail of their warrior. And so that there are even more pages on forums to discuss – which one is better, the regular upgrade or the alt?!

BUT HEROES WITHOUT A SPECIALTY?? THAT'S TERRIBLE!!!

Look how many specialties are banned in the third game! And only a few selected heroes are taken into the main party – the rest are only used as cannon fodder.
Heroes in the 4th game have classes – combinations of skills. That's real progress!

Ifrits with orcs, humans (rogues are humans after all), nightmares (because in 3 they are neutral, in 5 they are from Inferno), dragons, and hydras???

It's subjective, but don't constantly hold down the Shift key.

Where did the siege weapons go?

What are they needed for?

And melee attack through walls.

Have you never poked a stick through a fence? Why take everything so literally?

And the caravan-sorai delivers everything in one turn!!

O_O Have you even played the 4th game? In one turn, the caravan will deliver the contents if it really takes only one turn to get there (I don't remember the exact numbers; I haven't studied it much because I don't use caravans)
