yes but massive AA doesn't affect the time it takes to charge the priority sector, you should still see the slow increase of the sector in the hud and red numbers poping up when you hit the planes but this is not starting. The skill should increases the instant damage and the cool down but I just get the increase cool down which start right away. If I'm using a captain without this skill on a prem dd for example it's working fine. I see the sector increase and the red numbers.
Maybe I understand the mechanic worng?
