I also feel like the Corsairs would have a bit of envy toward the Phantoms. Look at the people who the Phantoms attack, last 2 big ones were the Mox Bombing of Cambridge, which the Corsairs would probably throw a parade for, and the assault on Aomorri, beating up on the headquarters of the GMG? Thats bound to get you some Corsair love. The Last thing to think about it the Corsairs friendly and ally list. It's very small, so why would we start a fight with someone else for no reason?
