Sure! If it were up to me, i would make Legendary Titles very hard to get, and i would also make sure they were exsclusive enough, so the 'Legendary' actually had enough meaning and value attached to it - in order for the few players that would work hard for these titles, could actually feel satisfied and proud of their titles, and other players would look up to them for that, and feel impressed.
I would also attach cosmetics to these legendary titles/commendations.
And when i say i would make these commendations hard-to-get and exsclusive, i'm talking about making them an actual challenge and not something grindy, which people with enough time on their hands could achieve, but a mixture of skill and dedication instead.
'Legendary Skeleton Exploder': Rewards the pirate with a full set of the special and sought after Gunpowder Skeleton sail, hull and figurehead.
'Legendary Curse Breaker': Rewards the pirate with a beautiful crafted mermaid curse outfit, including hat, jacket/dress, trousers, gloves, belt and boots. This outfit would be greyish/blueish color-themed, addorned with sapphires, emeralds and rubies to reflect the event.
