I was really disappointed by the lack of atmosphere in all sieges and assault in the civil war questline. The speeches are cliched and boring and no one has a plan besides charge and kill everything but those cant really be fixed. What could be fixed is the very few men and their very few corpses instantly fading. I would love a mod that does that. A lot more atmosphere for larger battles. A warzones style spawn adjuster would mean that those with less beasty computers could also handle it. I tried doing this myself by changing iRemoveExcessDeadCount and iRemoveExcessComplexDeadCount but either they didnt do anything or I did something wrong. They fixed the corpse fading issue I had with warzones though.
