Riddles just don't seem worth the time at level 30 hoarders a riddle can take anywhere to 10-30 minutes depending on the island size and how fast you are able to locate the targets on the riddles, some riddles have 3-4 separate parts and on an island like Old faithful that can take some time or that big island to the north west corner of the map I forget the name.
On the other hand... a treasure map at level 30 can have anywhere between 3-6 chests per island and you basically are told where they are located you dont have to go looking around. You know the general area and can figure the rest out fairly quickly.
They both yield the same RNG chests so the treasure map with 3 chests cou ld yield 2 captains and 1 marauders where as the riddle which can take 10x longer can yield 1 captain or even worse a castaway.
Riddles are just not worth the time invested for the little gain, cancel the riddles pay the 100 gold and keep rolling the gold hoarder till you get a bunch of treasure maps from him seems like the only viable way to progress at a decent pace.
