To quickly touch on the "More heal intensive fights", to be clear with what I was talking about, Im not suggesting that healers only heal. I expect there to be down times where healers contribute to damage dealt. But having hte fights a bit more healer intensive OR more mechanically demanding so that there is less emphasis on 'downtime' where you will notice your dps usage and its limited options.
To go from
Broil>Broil>Broil>Broil some more> dot/RuinII with Energy Drain, some more broil, Adlo or Lustrate, back to Broil, etc
to
Broil>Adlo>broil>Broil> Lustrate> Ruin II> Lustrate> Bio>EDrain>Broil> Adlo>Succor> etc.
You jam in Broil, Bio, etc when you can and healing when necessary. I know Im not using like 90% of the skills but Im just trying to illustrate that increasing the healing load and incorporating mechanics which prevent you from sitting there and straight casting Broil would probably help mitigate against how boring it is to play the class. Heck, some of these things can be spruced up by having bosses cast mini tank busters. Busters that do % based damage that can be mitigated by shields/CDs, or have the boss do raid buster followed by tank buster followed by raid buster at a point where you cant LB3 it. I am obviously not a genius at encounter design, but there's a lot they can do to modify difficulty without overhauling every last aspect if people are willing to go for a different play style. If all healers want to do at the end of the day is manage dps skills and toss in heals or let their fairy do that work, then this wont work.
If they wanted to add more to the DPS (which I think is the wrong direction IMO but oh well - devs choices), then I would say it should not be by adding in the old skills but by adding complexity to how damage is dealt. Possibly up management of the fairy so that it does have DPS some skills attached to your gauge or where your fairy deals damage for you so itd be more optimal for a burst window for you to use healing while your fairy damages for you. Im more opposed to "put a dot on here, use an oGCD on CD there and bam - thats complex and engaging!", and that for the sake of class identity, if were gonna debate about that AST is about using cards to buff and RNG matters, then it would also be appropriate to say that SCH needs more fairy management, and not damage skills.
