I also agree that micromanage is absolutely perfect if it has a well-made AI controlled alternative. Micromanagement can = barely surviving against a much superior AI foe. (or a bored human one)
What I would like to know on the units, is how commonplace Cavalry units are, and wether you simply need to build a stables first, or if you have to find a free-range herd of Horses to slowly domesticate.
Also, if mounted units (like cavaliers, horsearchers, Men-At-Arms, and Cataphracts) can mount and dismount. I would really only see Men-At-Arms or Knights (heavy armor) actually wanting to dismount in any circumstance, for instance taking a city and/ or fighting in close quarters.
Another question of Unit availability is Giant Spiders and Dragons. Will you be able to capture these units? Would a dragon require you to defeat it in combat AND pay a large gold tribute? Would a spider join your side with defeat plus some magical artifact/ artificer? Is there some kind of beastmaster unit that can capture lesser creatures soley through battle, like Cyclops, Giant Lizards, and Giant Tigers?
What lengths say, would I need to go to for a primarily cavalry army spearheaded by a great Dragon? possibly some giant lizards and giant spiders as well.
//And yes to customability, it would be great to have a custom-elite core called the "dragon core" loyal to Soverein first and Dragon second, with some giant flame emblem on their armor. and/ or tatoos.
