These look like good changes, but like others I have questions about the location of the War HQ. I’d like to see them be limited to a high-sec region that the defender has a structure in. Older high sec pilots who grinded missions to put down POSs are often limited to half of space.
Alternatively, you could just remove the KOS effects from negative Faction Standings. Or create an item similar to the tags to rep security status, for faction standings. Or give me an infinite coffee pot so I make more sense at this hour of the morning.
