Yep, beseiging longer causes losses to the beseiged every turn, definately worth it lest they have reinforcements.
The main things I want to know is wether AP(Armour-Piercing), attack range, AC(anti-cav), different defenses(The whole stuff about missiles ignore skill, guns have ap ignore sheild and skill), morale, reload time, # of men in the units, Extra-Hitpoint units, and the movement speed of units(especially cavalry) are taken into account by auto-resolve.
If it is just simply taking the stats, stacking them against each other, and applying bonuses then I am totally doing everything wrong, because when I build armies, I choose which units to use based on speed, AP, range, morale, upkeep, and of course stats too but paying attention to the different types of defense. And decide which units are worth using by cost vs. overall effectiveness.
If the full stack of cavalry gets beat by 8 cannons, then my logic of auto-resolve needs to go out the window...
Edit: SwampRat, You know if the seige defender bonus from archers applies to all/other ranged units, Javs? Crossbows? Seige weapons?
