To take it another step, there should be negatives for bombarding a city with either mortars or aircraft or modern navy.
In the “Total War” series you damage city buildings when using heavy bombardment.
Once you capture the city these buildings are still damaged and NOT functions in full capacity.
The player then has to repair them and that cost money.
This concept is forcing players to be more mindful about how much bombardment they use.
