I'd love to see some sort of flanking mechanic. For instance: 2 ships that both have the same opponent in arc, while neither of them are in arc of that opponent would get a bonus to attacking that enemy.
Maybe some sort of dice modification, or an extra die, a free action even regardless of stress.
Or heck! Maybe "flanking" could be a new keyword, and various titles could give different effects if the circumstances are met.
And done right, this could be a soft buff to Firesprays, as they have 2 arcs with which to both flank and deny flanking.
