I have a few suggestions / wishes:
1) Please allow more variety when it comes to battle set ups. Expand the setup zone, and / or randomize how large it is, and where it is (and make it optional, for those of us who don't want what I am suggesting). Sometimes a lot of the map is off limits because the set up zone is relatively small, and if there is some good terrain for defense, or a clear lane of open ground for an assault, or a forest through which to sneak a flanking force, I am unable to take advantage given the setup zone and the number of turns available.
2) Larger maximum map sizes would be great (only limited by the resources of the computer).
3) A greater number of soldiers in a given battle would also be nice.
4) Implement larger unit model sizes to provide a better sense that many thousands of people are present on the field. Instead of 8 soldier models, how about 16, 24, 48...? Whatever the convenient upper limit might be. I suspect that doing so might require some map adjustments and other work, but it would look pretty impressive.
5) I understand the mechanism where some units will push forward after an enemy falls back, but that should have some additional A.I. built in. It shouldn't ALWAYS happen, because it isn't sensible for a unit to assault, force an oppoent back, and then advance right into the middle of other enemy units, only to be flanked and routed the very next turn. I realize the player should judiciously time assaults with such units and properly support the attack, but I think it also makes sense for the units to utilize good judgement and not get themselves destroyed by advancing too far. And...sometimes they SHOULD advance too far and get destroyed, because that actually happened on occasion.

6) This wonderful tactical game, in my opinion, SCREAMS for integrating a deep strategic layer. Political complexity of Crusader Kings II + some elements from Medieval Total War 2 + FOGII for playing out battles = awesomeness.
-Crusader Kings 2 has some great management stuff, and I love the idea of developing a proud lineage (or not so proud) throughout the years while keeping the other powermad people in the kingdom at bay, but the battles are awfully boring.
-Medieval Total War 2 presents fun battles, but there were many things that were quite wrong, and the AI wasn't exactly spectacular. TW games since then have gotten more and more ridiculously unrealistic and over-the-top.
You guys would have a major hit on your hands that would embody believable battle outcomes on the tactical field plus alliances, economic, and strategic management. Throw in the court intrigues and the challenges of keeping an ever-growing empire faithful to you, and multiple human oponents available online... I'd never leave home. Of course, make everything optional in the settings screen. If someone doesn't want the CK2 level stuff, for example, they can turn it off.
Thanks for reading!
