I’m not entirely sure why you’re having difficulties differentiating between war HQs (a mechanic implemented by CCP to specifically act as a requirement to declare outgoing wars) and structure ownership, which is a requirement to be open to attack. I’m sure you’ll get there at some point though, just like you did with your viewpoint about ganking.
Please give me a moment while I search for my tiny violin, so that I can play it for the five-digit-member alliances that are so unjustly bullied by my presence, and can’t deal with non-consensual PvP harassment from a single player because they have much more important things to attend to, like maintaining the botter ISK farms that are paying off their leaders’ second mortgages.
