Why, they dare to attack another player in a competitive sandbox game without asking permission first of course. Those wardeccers don’t arrange in advance for an honourable battle according to the eBushido Carebear Code, but rather deign to engaging in spaceship PvP on their own initiative.
So, your idea is that in order for me to remove your Engineering Complex that is jacking up the industrial indices in my system, I have to become an enemy of the local NPCs and both fight you and your defence fleet, as well as the Faction Navy for the hour or more it takes to explode the structure? Talk about wanting to tilt the game in your favour.
As for the second idea, while I hate station games as much as the next guy, locking people out of stations seems a bit heavy-handed and would tilt the battlefield significantly in favour of one side. Therefore, if station docking is such an issue that needs to be fixed perhaps both sides of the war could be locked out of the stations so that things are more equal? Or maybe it would be simpler if you really don’t want people docking in “your” station, you could actually deploy a private station and use the access control list to prevent your opponents from docking there.
But ultimately New Eden is suppose to be a war-torn place. Wars are suppose to exist, even ones declared by ‘cowards’. I see really don’t see the issue you are trying to workaround as is the nominal purpose of this forum section. Everything is working as intended.
