damaged defense buildings
Not sure if this has been suggested but I didnt see it in the search results.
My idea is that if a defense building is damaged but not destroyed that it suffers some penalties. For example if an archer tower is half health maybe 1 or 2 archers fall off or maybe there aim is alittle off and have a small chance of missing their target. Morters and cannons could work the same way as they could get a crack in them and have bad aim. Maybe wizard towers would get smaller and reduce their range of attack.
Any thoughts?
