Tightly bunched systems, like those in the Core could use some reworking on their placement on the galactic map. Some planets are so close that the hotspots for their interaction circles will overlap each other, thus making some actions like moving a unit in to orbit impossible or insanely difficult.

I think it's awesome you provide so many planets and I realize there's only so much space to work with but still this can become a serious impediment in specific contexts.
