Ahh, I was also thinking along the same lines for the ambush effect if what I originally proposed would be hard for the AI to understand. I think your proposals for them are good. What do you think of there being a 10% chance that the ambush promotion is retained by the unit if it is successful in the battle (obviously).
I was wondering whether the units would become more specific in terms of being specialised against other unit types, so that basically makes up for that, I completely understand what you say about archers being very tough city defenders, bombarding was just annoyng for me because the AI would send over a stack where one unit was much stronger than the others and it meant I could only bombard that one unit and not that effectively, as I hadn't researched any seige weapons yet.
Also, I like the idea of influence changing with battle outcomes, but it seems quite strong - if you're attacking a unit much stronger than you and its within your boarders you expect to lose a unit or two to save your improvements but then you can lose lots of influence on your boarder which can be really significant, also I even lost influence when enemy units pillaged my improvements, annoying - but the overall concept is fun.
