Define "that close" please. I'd really not say that 3K is necessarily that bad. Of course it's not good either, more distance would be more prudent. But we don't really know how much "3K" actually is. The actual distance from a planet's surface to 3K away from its outer atmosphere isn't exactly a small deal.
Anyways we're kind of nitpicking here. I never had anything against people attacking me near my bases, by the way. Please ignore the usual hotheads who always find a reason to complain about that stuff on our side.
I don't really expect people to RP I've got defenses I do not in the actual game.
Once again, the main guideline and the main issue is if an attack in a heavily armed enemy system is a guerrilla style in & out or not.
