This may be something that isn't even possible but wouldn't it be cool...
1. Remove all sotd from all zones except golden age ruins.
2. Add one large island (like the ice cave island) in every zone. This zone would be bases for undead with buildings and all.
3. Have the island patrolled by SOTD that cant be pulled very far from the island.
People can raid these islands and kill the boss. Enter the chest area and loot lots of resources. Respawn of several hours minimum.
Would encourage more pvp boat battles and spread out the fighting. Would also be an alternative to harvesting resources. (maybe make the loot rare resources.) Would also be more pirate type content.
