NFZ stuff is just one little point which will be better to make when you add this. I'm talking about it in general.
in general: only enemies should have a disadvantage close to stations. its totally in RP to hug a base if it belongs to your faction/is allied with you to save your live.
/edit:
give all station Isis firepower or more + more turrets to have no dead zone to sit in AND add energie drain bubble to freeports could be a solution:P
