Well, if Nival created such a canon, couldn't they have preserved it in Heroes 6 and 7?
But in general, we've strayed from the topic.

It's unclear what justifies the weakening of the skeleton archers. And the base stats are significantly reduced: HP is decreased by 1.33 times, which is far from comparable to the protection against arrows for a melee unit. In this case, it would be necessary to increase the Initiative to 12 or more. Or apply the arrow protection buff to the old stats. Or penalize the maximum Initiative by -1.

Bone Archers
1/2, 1-2, 5, 4, 10, Undead, Marksman, Protection from Arrows
Bone Champions
2/4, 1-3, 5, 5, 10, Undead, Protection from Arrows, Protects Allies, Stunning Blow

if Titans are given a mechanic, then it makes sense to give Goblins the ability to repair up to 3 times.

Nope. It's cheating.

So, is it just to repair golems once, gargoyles once, and titans once? :)
Oh, wait, I'm getting mixed up; the mechanical gargoyles were somewhere else, not here.

mechanical gargoyles in Heroes 7
in general, I also made the Titans as constructs, but with gargoyles, this is just absurd.

And what about the other factions? Are they all balanced, or will the mod be further refined?

What about the balance of the other factions? Is it okay, or will the mod be further refined?

It will be further refined. I am currently working on updating the Necropolis and Academy factions and adding the Inferno faction.

So, now we have 3 living creatures in the Academy (gremlins, mages, rakshasa), 2 elementals (gargoyles, djinns), and 2 mechanical units (golems and titans).

So, now we have 3 living creatures (gremlins, mages, rakshasa), 2 elementals (gargoyles, djinns), and 2 mechanisms (golems and titans) in the Academy.

Why are gargoyles elementals? Why aren't they mechanisms?

Why not mechanisms?

Because it's cheating.

Regarding immunities for the Academy: In the next update, stone gargoyles will have immunity to Earth and Air, obsidian gargoyles to Earth, Air, Fire, and Water, and marble aurals to all elements. But here's the question: who should get immunity to Air: titans (since they control lightning themselves) or djinns (which are naturally related to Air)?

As far as I understand, djinns by their nature are not related to elemental magic, but to primordial magic, i.e., immunity to air is not justified for a djinn, but 50(75)% resistance to magic is quite acceptable. Regarding titans - yes, they do control lightning, but does that mean they should have immunity to it? They are not elementals, but mechanisms; it's one thing if we try to extinguish fire with fire (futilely casting a fireball at a fire elemental), and another thing if we throw a projectile at a cannon that shoots these projectiles itself.

Because it's a cheat.

What exactly is the cheat? Oh, so they can be repaired? Why not? Or is it about the extra skills on constructs? Like morale, etc. Why not that either? Elementals should be djinns, dwarven dragons, and ents. You could try justifying a unicorn as an elemental (it's a creature of light after all).
