Oh no, by that post I made, I didn't mean "Tweak the worldgen". That would be absurd. I was talking an optimal scenario for the player's end. When you have 7 useless hops near your home planet, you have to actually take planets to avoid deep striking that wouldn't provide you anything useful to actually get to the juicy (and clustered up) bits. Same problem in reverse if everything's really closeby. You have to deepstrike or take useless planets to link yourself to the AI home planets and make them go boom. The optimal set up is somewhere in the middle, where you have the occasional juicy planet within 3 hops of the last one that you took.
So in short I was stating the obvious.
