Honestly it's surprising they haven't done something like that for the Rising.

The only ones who got any of the sort was way back when in the early years.

of course it's the Rising, nothing much to say or do special for. But if they make things more impactful for the players accounts overall. then it might just make sense for those who not only have alts, but one character only.

We can't really do much for Moonfire, as Costa basically gets repurposed.
Although what they could do with a specialized instance would be far, FAR GRANDER, than that costa could supply.
Almost wish It wasn't at Costa to begin with.

NewYears/Heavensturn could involve something more personal. Though not as necessary as other things. But they could make it more personal regardless of any ties to the world or not.

The Easter(forgot its name) could have a small set of rotating games. Maybe even a Repurposed Treasure Map/lookout mechanics to find "objects". But that could just be a seasonal Fate.

Little Ladies and Valentines is a given on what they could possibly do for it.
(The one difference, it would either change with the year, or the decorations will be tame outside of zones within the instance. in said specific sectioned off areas could the decorations be pushed to 1000%
