This is espically true if you watch the tactics video.

The AI now has a plot. So when you go at them, they say, ahh, I have this many calvary, this many infantry I am going to try and do this formation

Then if you scatter them they are going to try and reform or try a new formation.


For formational combat with lines and formations marching, it is rather difficult at 10,000 let alone at 20,000, 30,000, etc.

I don't know coding but I do know science, a controlled variable is always easier to test then a variety of uncontrolled ones.
