Camping for health regeneration
i haven't played the game since the last official patch, but i was thinking that it would be helpful for you to be able to make camp for your army in order to regenerate its health while out in the world. perhaps it would be better to just tie it in with the fortify function instead. there could be spells, equipment, or specialist units(cleric, medic etc.) that would make healing faster while your out there.
Although i think it would be better to not have it tie in with fortify and actually give you a negative to defense mainly because you might be unprepared for an attack because of the units that would be in beds out of their armor and whatnot. sort of a trade off with a bonus to health regen but also more vulnerability.
