So, as a lore/story nerd, the Old Life quest is my favorite for the New Life event and I always loved the concept of it. There were already very few ghosts as is, but even major ghosts/spirits have not been updated since Blackwood. I'd always hoped that more quest related ghosts would be added over time for both big and small quests because seeing characters we've lost over the years was really interesting.
Solstice Spoilers
Post-Solstice, however, there is a new problem with the ghosts that appear. Today I had Prince Naemon appear during the daily after completing Choice and Consequence, a Solstice side quest involving Naemon's resurrection. The quest has a choice, but it does not end with Naemon's death, only his petrification if you so choose it.
Considering Gabrielle's death after her recurring appearances throughout the game, it also feels very odd to not have her spirit added either this year.
I know it's not a big thing compared to other updates and issues with the game currently, but it'd be really nice to see this quest updated for at least major story quests again. I do hope we get other fixes next year both big and small but this is definitely one of them I'd really like to see.
