An interesting phenomenon.
It's the beginning of the second map; I need to break through a block of 50+ Marks with a Great Serpent.
In the tavern, I hire Valeska, but I don't have enough money to upgrade her "native" archers.
The result: 36 grand archers, 11 regular archers, and 11 copies (1+7+1+1+1).
Neutrals are in three stacks.
The first volley against the upgraded ones almost wiped them all out.
So, throughout the entire battle, the neutral Marks only attacked the un-upgraded archers, resulting in 6 losses during the battle.
Why did they prefer the regular ones?
Reducing your attacking potential is the AI's main goal. Un-upgraded creatures can be upgraded during the process, and it's easier to kill them. In other words: it tries to suppress potentially dangerous units in their early stages. :smile08:
