First change.
Have three barrels float to the top after sinking a ship. A percentage of the cannon balls, planks and bannanas.
Second change.
When your ship sinks you are taken to a different instance of the world. So if your ship sinks or you sink another ship. The crew of the said ship spawn in a different instance. Nothing worse then trying to do a quest or skull raid and a crew comes by and starts to attack. I get it,. The seas are perilous. Not asking to change that. But you kill this other crew then they come back 10 minutes later . Still with no treasure . Just there to prevent you from enjoying the game.
