On Expert difficulty and higher, AI heroes always have Immortality cast on them. Just one. There can be no room for misinterpretation or misunderstanding here. Or is this about realism? :D

The official information from the developer has already been accurately quoted by Lu:
"At higher difficulty levels, AI heroes drink a potion of immortality before battle."
So, what about the possibility of misinterpretation?
It's not worth selling bugs as features. People will buy it and accept it, of course, but...

At least the summoning and necromancy menus.

No, it doesn't work for offline mode. It would be good to have the ability to summon into an empty stack, rather than on top of already upgraded/buffed units. But there isn't.

The thing is, people often play both online and offline. It's impossible to do this on two different versions – it creates confusion.

Yeah, there's that. And even though I only play offline, it's still annoying.

No. That's wrong. The program doesn't send anything anywhere, so you can't label it as SpyWare, no matter how hard you try.

Independently sending some kind of information is not a mandatory item in the definition of a Trojan. "This fool will send it himself" is a bad position.
The program works in favor of a subject who is not a necessary participant in the use of the program. At the same time, it gives this "third party" opportunities that are not available to the average user. And these opportunities involve providing information about the aforementioned average user.
If you object, saying, "it doesn't format the drive," I'll agree. Let's be happy together :)

The first thing that catches the eye is the scale. I've never heard of such competitions, let alone seen them. There's nothing more massive ;)

Well, apparently, you're not interested in this form of life :) Participants of, say, "LADA Revolution" would be very surprised by the phrase "the whole planet is playing Equilibris." So what?

It's incredibly interesting. When will judges ride on some other version of the game than ordinary mortals in some tournament?

They do. The version is the same, but the possibilities are different... Of course, "these possibilities are not needed by anyone," but usually players are used to deciding for themselves what they need and what they don't.

To run a tournament on a demonstrably worse software just to attract those who simply feel like galloping on a horse? A worthy undertaking, very promising.

If we're talking about the offline version, it's unclear where and by whom the "demonstrable inferiority" has been established? The list of improvements is known, and there are very few of them. But the list of added bugs is open and has a tendency to grow.

People are not ready to replace stale bread from the store with homemade bread, because "what if guests come, and they will only eat store-bought bread."

For homemade bread, the fact that someone spat on your slice when cutting it is a very big drawback. The message "it tastes better" is heard, but it doesn't increase the appetite. The message that "we will spit more deliciously on your next slice" is also heard.

There is a version that is accepted as a standard for playing in any interportal or world competitions.

I should have made fun of

Only FOR!!! ...
...So, when the whole planet plays Equilibris...

earlier. Now, it seems that the methods of air vendors are no longer considered impolite in this discussion?
*I'm not saying that promoting Equilibris = selling air. I just don't like the methods. Especially when they lead quite adequate people astray.
No offense, with respect, and so on :)
