I'm sorry I didn't make it clear.
In fact, in previous versions want to use free units to prevent snowball.
So you can see AI lord will get 20-40? free units in an instant after being defeated.
All of this can be seen in 1.2 (or earlier 1.1?)
So they can have a lot of recruit units quickly ( and going to die )
1.3 To change AI's recruit army , AI can own more free elite units.
I think the direction of this update is wrong.
We must improve the diplomatic system and make the AI more smarter
(to make sure AI has time and intelligence to training the army)
Not by cheating
