Total War have been one of the few strategy games that acknowledge the importance of morale in warfare (specifically, battles), which is great.
However, as the series progresses, I wonder if its time for CA to consider portraying morale in a more detailed and impacting way.
So far, while units have morale in battles and it affects their performance quite realistically, there has been no morale in the campaign map. Army morale while on the march, while camping, besieging and defending has always been extremely important and no less so in this time period (18th C). Armies would frequently suffer from disorder, desertions and general loss of fighting spirit in between engagements as well as during them.
I would like to see CA include morale on the campaign map, even if its someting as simple as settlement happiness. Numerous factors could contribute to it, such as the General's command rating, his personal traits, the army composition (quality of troops, culture of troops, mercenaries etc), the army's current location etc. In turn, the campaign map morale could influence other aspects, like desertions (like we have in M2TW with Crusades), marching speed (or range, depending on whether they choose a real time or turn based campaign) and should off course translate into the starting morale in battles.
I would understand if CA chooses to not implement this themselves because of time constraints, but I would nevertheless like to have at least the possibility of modding in this option.
