If I'm honest.... I'm prolly that player that would "just want to heal". That's not saying I don't dps in down time where there's clearly nothing to heal... But rather, I'd prefer being able to fulfill my role in its avenues specifically to mitigate/protect/heal my party over deal damage. However.... I do appreciate design in where this concept it coupled with a reward of extra damage. Things like how Holy causes stun, and thereby is a form of mitigation while dealing damage. Or how WHM gains a blood lily for healing and etc. I like these concepts of "you're doing your job well, here's something akin to a reward for your job" type of deal. So far on AST, I'm mashing malefic and keeping up a dot... I know I get earthly star but that looks like a "plant it and let it be" type skill like DRK's salty earth lol.
If every job could get a form of synergy in what their dps is with their healing capabilities, even if it's subtle/small... I'd like that. I don't want the job to be "when can I stop healing so I can go back to mashing 1 and dotting again"... Rather, "I can't wait until I blank enough so I can provide blank". I don't want to be a dps with healing capabilities I guess is my point here... but I do need something that synergizes with what I do to give me some form of "feel good" thing. Whether it's you do healing/cards enough you're rewarded a fantastic self bonus, group bonus, or mitigation or guaranteed crit heal, crit on a damage skill... ANYTHING like that would be nice. It doesn't necessarily need to be "you do higher dps cuz you heal gud" either. As I typed this, I realized I think the only thing I get a high from AST atm is all 3 different seals and getting to use divination but.... trying to pop it on everyone in the group when they're spread out and the fact cards are a chore kinda nullifies that feeling sometimes. It's a short duration and long cd too.
I won't say I wish that all I had to do was heal. However I will say that for all I have to do on AST so far, I'd appreciate more noticeable differences or more enjoyable buffs that make me shine with this job over the other 2 just as they shine in particular ways over the remaining 2. I shouldn't need encouragement to dps as a healer, or a feeling of "relief" when I see everyone's topped off and I can continue casting malefic. I should feel a sense of accomplishment and pride that by doing what I do best, I'm rewarded with something to provide to the party or myself that others cannot provide. I feel like the former cards were a bit of that, maybe not as much of a buildup but just knowing you had the power to hold cards for specific situations sounded like AST was a utility healer. It didn't excel particularly in any one situation, but it looked like it could adapt to whatever situation it was dealt with.
This is only speculation though from what I remember seeing out of AST's back in the day. I remember boles saving people on the final boss of Sohm Al Hard because that mitigation could let a dps take the tank buster and survive. It wasn't that it was necessarily required or needed, but the fact "you could" and it showed for it.
