If your doing Treasure Maps for the Loot, your doing them for the wrong reasons.
Its not the Destination, it's the Journey. Taking the map, looking at it, trying to figure out what that drawing is referencing and then finding that place on the map is the fun part of the treasure maps.
If all you care about is the loot, then get the Treasure Map addon and you won't spend more than 5 minutes on a treasure map. Or sell the thing to people who do enjoy the journey.
