[SUGGESTION] Rebuilding Flags
I think it would be a great idea that if a building is destroyed it is replaced by a miniature flag. Like a normal flag it would take a specified amount of time to capture. Once captured it would be replaced by the building. The strength of the building would determine the ammount of time taken to rebuild. Also the building could get stronger each time it is resummoned to balance out with a stronger battlefield. I think this would add a new interesting gameplay mechanic to the game. It may make matches take longer so perhaps it should be a toggleable mode.
