I only ever do riddles for Athena's Voyages or if there are more maps for that island which is a shame because honestly I love riddles. I think they're really fun and I like doing them I just feel the reward is very unfulfilling and tarnishes the experience
It's not about the level of chest it's about the quantity. Why search a whole island for one chest when I could have 6 chances of getting the same chest on one island by digging?
Of course it would be fine if you still had a chance of getting one chest, it would just be far more exciting if you had the opportunity to find big clusters of chests stashed in a single area
