I agree we need to get something for destroying Powerplay faction ships that interdict and attack us. Currently they only give at most a 200 Cr bounty from them assaulting us if they are not the same faction as the faction that controls the system we are in. I have been interdicted by Archon Delaine ships while traveling in a system controlled by Li Yong-Rui while pledged to Aisling Duval.
That is to say without using faction names but numbers showing faction differences: being interdicted by faction #1 in faction #2's system while pledged to faction #3, where all factions are considered hostile to each other. Even though I was technically trespassing on faction #2's territory, both faction #2 and faction #3 should be rewarding me for destroying faction #1's ship, with faction #2 rewarding me for destroying an invader, and faction #3 rewarding me for destroying an enemy vessel. I could understand faction #2 putting a bounty on me if I destroyed one of their ships in a system they owned, but I not only helped my own faction (faction #3) but also faction #2. There should be some reward for doing this and it should be better than the assault on another ship bounty that the interdicting ship incurs.
