If the planets could be mapped in the visible sky, I think you’d just see a very long dipper tail. The way things are going, T7+ will likely be at the end of the new T6 worlds; continuously making a longer line, always requiring you to go to servers in a different region in order to portal to them.
We tried calling out the need for a planetary placement re-balance after the new planets were added:
It went unanswered as far as the devs go.
