Rome II had a graphical option added called Hide bodies, it was REALLY useful for people who didn't want battles with many reinforcing armies to turn into a slide show when looking at a massive mound of corpses.
It was useful since I don't want to have to lower my unit detail to low just to get rid of corpses.
Low unit detail makes troops LOD look like paper cutouts not to mention in Warhammer II and Three kingdoms it causes generals to look very bad in battle for some reason even when zoomed in.
So please CA I can't imagine that this is a difficult option to add, I mean you already added it all it is is removing corpses or even better make one that is a slider for body count limit.
PLEASE add it.
