Honestly, don’t think funcom can do it. From what I have been told the game is pretty close to it’s limit. To add very limited piracy; because they can’t make the map bigger, you’d have to give something else up.
Now I personally would love to see pirate raiders added for all those water bases.
And with the new raider treasures you have to carry, we need rowboats. Because you know what the servers are going to be like with everyone building sandstone bridges all over the map.
