The unique card buffs had a whole host of troubles and if they added it back the job would be nigh-unplayable. I do wish noct/diur sect was back, but unique cards (a la stormblood) should die and stay dead. If you have 6 cards that all do 6 different things, there will obviously be cards you want to draw and cards you don't. Ie the 'fish for balance' gameplan of stormblood that was very unsatisfying. If none of the cards are a dps buff, and are only utility, then you can't plan your healplan around them bc you have to assume that you will not get the card you want for every possible situation. It's what happens with MA on a much bigger scale. Which would again mean the cards would be useless, since your entire gameplay would play around basically not drawing cards, bc whatever you draw would not matter beyond a small bonus which just... isn't really relevant. Unless the cards had a way to draw the one you want for each situation which at that point, what's the point of making them cards. Just give it 6 new generic abilities. No, cards should remain dps buffs bc if all 6 cards do the same thing, it's actually possible to play around them. It just requires reactivity to determine where they go rather than a cherry on top of an already solid mit/healplan. I seriously do not understand the desire for stormblood cards returning bc it was not fun at all.
It does need more time mage abilities but like... you are on every healer post requesting that scholar or astro become necromancer. Why not just ask for that as a new job instead of wanting old jobs to completely be stripped of their identities?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.
