Which monster do you like the most in Heroes 5 at level 7?

Nobody likes him at this level.

Well, that's true.

Neither in appearance,

Something's wrong with your aesthetic perception, that's for sure.

nor in physical parameters.

And the same goes for the game mechanics.

What is there to say if the dragons of the Forest faction are not stronger than an Ent?

First, they are still stronger (in terms of total Defense and HP), and second, a dragon is an attacking unit, while an Ent is a defensive one. And it's specifically designed for solidifying defensive formations. So you need to imagine the whole picture, not just isolated parts.

They hit harder, have higher initiative, but it's not worth paying several times more for them, especially for the upgraded ones.

And what should you pay extra for, and why? Isn't that enough? Considering that initiative is one of the most important parameters, and a strong attack will reduce the retaliation. This isn't a simultaneous exchange of blows like in Heroes 3 or 4, don't forget. Here, the first strike decides a lot. After that, a second strike may not even be necessary.

And as for the spectral dragons... I won't even comment.

Take the Astral Dragons.

The Archangel, from a powerful man in heavy armor with a huge sword, turned into a cute girl, but that's not all.

Do men appeal to you more?

They also made the flight and attack animations frankly funny and silly.

It's a matter of taste...

The devils turned out to be too simple. They teleport less effectively than in Heroes 3 and 4.

See the point above.

And they don't make such frightening sounds anymore.

Oh, yes! The most important thing in Heroes is the frightening sounds!

The Titan was deprived of its elegant armor, and the melee attack animation looks clumsy.

Well, and of course, the strength of the Titans was in their elegant armor - who would argue? And the animation is quite decent. Or do you suggest that an unarmed Titan should hit the enemy with its head instead of its leg?

Well, all the dragons have become skinny, small, and not as strong.

Of course, dragons should be big and fat. Come on, man. Dragons should be dangerous first and foremost. And that has been successfully implemented.

The partial vulnerability to irresistible magic of the black dragon has finally angered me!!!

Well, yes. It's annoying that you can't cheat anymore...

What's the point of a sorcerer learning irresistible magic if Armageddon will also kill the dragon?!

Of course, there's no point. Because there are no other spells besides Armageddon...

In short, the Black Dragon from Heroes 5, in terms of appearance and power, cannot be compared to the Black Dragon from Heroes 4 (that was a real dragon, a terrible dragon!!!).

That's an incorrect statement. The Warlock is now a real Warlock, a terrible one. Against his background, the dragons have faded.

And almost the same can be said about the Cyclops!

It's clear that you haven't seen the Free Cyclops with a well-developed Barbarian. In conclusion, I'll say: a grade of 2 for your post. Study the game mechanics, watch replays.
