Since every unit has its own experience and moral level, so why must we let a whole stack army's morale solely determined by the general which leads them?Every unit should have its tradition, its honors and dishonors, etc.
If some troop just sustained a humiliating defeat, their experience should not suffer much but their morale must go down drastically so they cannot be on their mettle to fight bravely again in some time. For example, all Roman troops who survived Cannae were sent to distant provinces for some trivial jobs, never got a chance to fight any serious battle again.
And if you let your troops rest too long, especially in some notoriously luxurious cities, they will become lazy and soft, as Hannibal found out when he led his once toughest-in-the-world army out of Capua after a winter's rest, "I still remember these armors, but I can't recognize those men in them.", I believe he said something like this.![]()
