I have been always suggesting that the AI lords go level up their troops more before joining armies or doing raids, not magically getting higher tier troops mind you, actually spending time building them. I have also always wanted higher tier armor to reduce damage much more then it does. These two things would help AI battles be more interesting without making them even more boring and annoying. Some battles are really ****ing hard IMO even with best troops and best tactics and experience. I disagree that stacking archers/HA magically makes every encounter an easy afk sandwich time fight.
I asked you before, but why don't you just use infantry if you think infantry fighting is more fun?
To many people, watching dog piles of infantry is actually not fun either and seems even more boring.
