I have an idea that may get the pirate legend grind real again, what if we added a chest or device that you get from an athena or pirate legend quest that allows you to use it once or you can sell it like the flaming skull but this device pings the entire map and shows you where all the players are for a few seconds, but the player that used the ping shows up like a reapers mark for a few seconds longer.
The other idea I have is smoke canon balls to lose ships chasing you or blind the person you chasing.
