The job died the momenf they removed unique card buffs and nocturnal/diurnal sects. It's a pity, because they destroyed one of the most interesting jobs in the game. Rolling back is something they'll never do, because it would be like accepting they ruined the job. Instead, they keep using their trump card to justify unacceptable dev laziness: "it's hard to balance". I swear I've seen the devs using that lame excuse literally every single time they're simply lazy to walk out of their area of comfort.

As per DT and since the job is due a rework once again, I'd turn it into either a dark healer similar a necromancer, or make it more of a flavored time mage, bringing back time dilation, nocturnal / diurnal sects, and card system from first iteration.
