What are some ideas for slightly more rare encounters in the future?
I remember from the first game when fighting against a Turtle AI there was a very rare chance for a "structure ball" formation of the AI that was very formidable. It took all 5-9 guard posts and grouped them up right next to the AI command station, and then plopped down 3 or 4 shield generators on top of the ball.
I'm hoping for something like that to end up as a possibility later on down the line, as a rare chance to see the AI actually use shield generators instead of them being defunct for the AI side.
I also remember there being rare AI command station variants, but I didn't really like those. If there was something deadly like a AI Missile Command Station on a world that you really didn't want to take (but it was in the way), you'd have to sit there and suffer the attrition every time you went through.
