Multiplayer Map Design?

Hey guys and gals so I was wondering that it would seem like a good idea that if for new maps being made they added enemy AI bases, like in Halo Wars. In this way it helps with early game rushes and what not. But as to the faction of the AI bases I would say to just make them Forerunner bases. Also add interactive environments and strategic key points on the map other than just power generators and watch towers. What do you guys think? O.o
