Then again, the devs can ignore everything and let us continue to "turtle" with insane amounts of guns at the first set of chokepoints... thus leaving stars as dead space.
What can we suggest at stars to provide an incentive to use them? They are wasted real estate, and defenders can easily go the static route on the only set pathways from the star... the advantages for the defender are always defences in depth, short supply lines, quick reinforcements, etc.
Without encouraging the use of mixed fleets in the open areas, the game will devolve into static Maginot-lines of guns with hundreds of zergling scoutships and hanger defences to chew down invaders.
Perhaps if there was an option to have a "Capture the Star" type play, it would force gameplay into the solar gravity wells, adding another element that prevents static repetition.
