A pirate expansion!!!!!
A new class: pirate!
People have begged for guild housing. But go one better....guild PIRATE SHIPS!
You start out with some leaky sloop but as you make raid progress you can upgrade your ship. You need a very seaworthy vessel to navigate to the end game raid entrance.
Also, guild PvP on the high seas! Board other guilds ships and sink them! Take them hostage (for an hour) or make them walk the plank!
You can practice on NPC ships to board and loot.
Pirates!
