When a building catches on fire maybe after a certain amount of time the place will actually be burnt down but only if like 60% of the fire is still left or if there are firefighters on the scene it wont burn down, but if it gets ignored it should burn down, kind of like the terrorist attack. And like after so many minutes the city will rebuild it.
Also; when a building is on fire players can not enter it, only firefighters to search the building, but regular players (like robbers) shouldn't be able to enter a building if it is on fire.
City workers (New Skill): When places get destroyed in a terrorist act these people will go to the scene and fix the buildings, making the buildings becoming fixed a lot fast so we can go back to robbing it, it catching on fire, etc.. We could also replace the Trash Master skill with City Worker and combine the classes.
Let me know what you think.
