UNIT - Creature Balance + Visual Changes

Does the tactic of endlessly prolonging a battle to fully recover losses not bother you?

There are no endless battles. The first-aid tent restores a fixed amount of HP - 100 units (without additional bonuses in the form of specializations, etc.). In the early stages of the game, this may be too much, but you still need to acquire the appropriate perk. However, in a longer game, the efficiency of healing is very low, and the tent mostly serves as a dispel. After 3 uses, the tent turns into a decorative element and negates all the benefits of upgrading the machinery and the perk for the tent, as well as all the specializations of heroes based on it. That is why I always preferred to avoid these skills and, when leveling up, choose practically anything except "the basis of machine control."

-Fire Demons (upgrade). Defense 5 (+1), Health 15 (+2), Damage from the "Explosion" ability increased by 250%.

It's high time to bring the ability to a decent level.
Additionally, I would also reduce the jump radius of the Alto from 8 to 7 (so that they can only attack with the tactic).

In this case, the damage from the ability will be reduced. If I remember correctly, the damage scales with the distance to the target.

As I understand it, Centaurs are currently bored on tier 2. With minimal changes, you can simply move the units from tier 3 to tier 2 (without changing characteristics or growth), and the Centaurs - from tier 2 to tier 3 (strengthening them to the level of Minotaurs). This significant change will actually only affect the Centaurs.

The Centaurs will definitely occupy tier 3; I just haven't had time to move them up a level yet. I would also like to note that the list of changes is not yet final and will be gradually expanded.
