While Rare said they plan on making previous Plunder Pass content available again but they're not sure the best way to do it, i thought about a possible solution that may work for everyone.
-Plunder Pass Exchange/Swap-
With this option you purchase the active plunder pass and swap the Plunder Pass and it's content with a previous one you missed.
While other players unlock the current content, you unlock the content from the swapped Plunder Pass.
However, it is a one time offer. If you missed more than one you need to consider carefully which one to choose.
Also you basically give up the chance to get the content from the Plunder Pass you swapped. A soul for a soul if you will (huehuehue...)
You may regret giving up on certain content but perhaps you will be happy with the choice you made.
This is just an idea. It gives players the option to get cosmetics they missed but keep a form of exclusivity since players that used the offer miss content that they swapped. Perfectly balanced...okay i'll stop.
It's unconventional but perhaps an option to consider. Perhaps. Perhaps not.
Cheers.
