At this point, there is more time-limited content than unlockable and buyable content, excluding the Pirate Emporium. It's a shame. Why would I care that you've done a short dig quest or watched Twitch 6 years ago? It's not reflective of your skill or anything you've accomplished, all it means is you were there at the right time in the right place. In most cases, I am better at the game than those players who flex their og reaper cosmetics because I've simply played much more than them and at a more consistent rate.
The FOMO policy has NO place in a $40 AAA game, no one is more deserving of cosmetics than others; I've played and supported the game more than most people who own 6 years old time-limited content I wasn't there to obtain, they are not privileged "early supporters". You support the game as much as anyone else at any time by purchasing it and making microtransactions.
To be completely fair, everything should be available in the shops through commendation unlocks since there are remnants and commendations that are similar enough to the og events, but at the very least, these items should be guaranteed to come back for an event that occurs once a year.
"But I'd rather have new items than reusing old ones" oh, you already own items we don't have... well that's cool... and really selfish of you. The Marauder's Medley event did it well, so it can be done again: introduce new content as the first reward, and reintroduce old content as further rewards so that people who already own these don't have to go through the entire event while other players do if they want the items. Even better to not waste game storage in fear of most people not clearing the event: have Larinna sell the old content for doubloons during the time of these events. The only advantage people who played earlier should get is to not have to pay as much (it would still be unfair but it adds incentive to play to get doubloons and replayability to the game).
Giving a wider audience access to more cosmetics that already exist and are just sitting in the game files taking storage space for the most part would allow for more creativity and variety on the seas, don't we all want that?
I want the Wailing Barnacle ship set over anything in the entire game, please give it back. I will set the seas on fire for it. No one who has it even uses it beside the wheel and capstan, so you don't ever see it anywhere.
