what about those who cant afford ss? those with market supporter status it would be unfair to them if they cant take or possess a planet, but the problem seems like planet stealers create an account then delete it after it has take a planet why not put a limit saying you must be actively playing for the past 3 months before being able to take a planet from someone, you can still have a planet if you do some exploring other than that you have to play actively for 3 months time meaning not just logging in then out at once, there should be real activity like upgrading, attacking for naq etc
another way i see it why not have a defense fleet? for just the def your planet system, def fleet esp design to protect planets
def fleet hangers must be built but its base not the ms already but the homeworld, these def fleet are solely for the def of the planet, since hypothetically all your planets belong to your system right?
if your ms is present it can complement your def fleet thus increasing the percentage of its def, but the sideline is that it will also increase your cost of repairs
and finally limit the number of hangers in your ms and def fleet, it must complement your army size as well as the number of planets you have, this is because the maintenance of def fleet is needed (they are always on ready alert compared to ms that can sit in a hanger doing nothing) a certain percentage of maintenance is taken from your naq production, this means you have to invest heavily on your up or army size to have a sizable fleet to be built
just a suggestion though
