The problem with this voyage is that it came out back with the OG version of the game. It was a different time back then where gold collecting and treasure value overall was way below the current average. Athena treasure like the skulls or trinkets did not exist back then. Furthermore, and in my own personal opinion, the PL voyage came out as a way for devs to hide the fact that the game was incomplete. Considering that all the other trading companies have gotten their own unique voyages now, a lot of people in the community believe that changes to Athena in some shape or matter might be coming soon. Although no one can determine the relevance of this matter, what I do know for sure is that it's definitely a popular topic. Some people believe we might get rehashed treasures, a new voyage, or even some sort of change to the legendary hideout.
Personally, I would want a complete substitution of the voyage. Something unique, epic, with a good story to tell, and one that merges different mechanics and themes from all the other trading companies to create puzzles, mini games, and over all a voyage that truly deserves the name of "legendary"
