Honorable Pirate
Excluding aesthetics, the seas are completely neglected during invasions. Have undead ships surround the island undergoing an invasion for its duration, or even have some bounty hunters (perhaps some "undead" bounty hunter ships?) mixed in to lure more pirates for mat runs and whatnot. Overall, more pirates would be attracted to areas of invasions to make them more eventful and immersive.
