Three long overlooked problems with this game.

[Hmr85]

Put back in the SOI and put some AI controlled AA drop pod guns on top of Primary facility's. I would link them to a Generator that's in the middle of the base and hard to get to. Any drop pods that come down in the middle of the SOI would be shot out of the sky.

If the enemy wants to drop into the base they would have to destroy the generator that hidden in the middle of it in a very defensive location. This would solve the problem IMO.
