I'd like to see the Construction Yard added.
Victory objective changes to:
1) Destroy Enemy Construction Yard
Or
2) Have most points when time ends
Destroying any other building awards a large amount of points, but the building is rebuilt after a few minutes by the Construction Yard (so you do it mostly for points, partly to lock out other team for a while).
A more extreme idea would be for all existing special infantry / vehicles to immediately die on the destruction of their related building.
Construction Yard should be particularly resistant to Timed/Remote C4 attacks, so it that it's not easy to just rush it early.
The biggest problem I have with the current system is that the loss of a building is very frustrating (limits your gameplay options, prevents you from playing the way that is most enjoyable) and yet is not punishing enough in terms of leading to a victory or defeat (as evident in games often lasting for a long time after a "critical" building is lost).
A Construction Yard would mean either instant victory/defeat at the destruction of the Yard, or a time-limited set-back for the destruction of other buildings.
