It's fun getting four famed from one loot run but it's poor for the game's overall feel of balance. Sailing's propensity for great loot disincentivizes looting in any other way. Why would anyone loot on land when looting at see is objectively, measurably better for getting famed weapons?
Keeping sailing as OP as it is isn't good for the game and it certainly isn't faithful to POTCO.
