The lighting can't stay like it currently is forever. No one will be able to catch Stormfish and Blackcloud Wreckers, and it is way too overpowered currently.
It needs to be reduced in the next update, but then even fewer people would care to start up the Fort of the Damned.
So I feel the fort needs different way to start it up.
What about putting beacons on different islands with the different colors already lit up? You would still have to spend time sailing around getting the lights. At least the white light could be lit up on a beacon. Maybe add a new beacon somewhere where it is harder to get up to?
A different way could be with these new Ashen keys. Be able to start the fort by trading/sacrificing 5 or 10 of the keys + a Ritual skull. More people would care to start it up this way I feel.
So if you start the fort with keys, the loot inside would be worth less compared to if started by lighting all the lanterns.
Whatever you do, the lightning needs to be reduced, but the FotD still needs to be doable. Reducing the lightning only will make no one care about the fort.
