useless scholars

[Atoli]

I think you need a lot more practise with the job if that's the case. SCHs can pretty much get away with not healing at all in dungeons and letting the fairy do everything. You need to make use of all your defensive CDs for the tank while DPSing and maybe manage your AF stacks better for those emergency moments. Maybe you've had an unlucky streak with all STR tanks or something?

If I don't heal together with my fairy, it takes less than 4 seconds for the tank to fall to 1k HP or less. I rarely get tanks that are a bit more sturdy, but even they are dead by the time I have applied and spread my DoTs if I leave healing to the fairy.
Even if I spam Physick/Adlo together with the fairy and don't dps at all, I've had tanks I could barely keep alive even with throwing 6 Lustrates at them. And it's not equipment trouble either, at least not on my end, since I kept pretty much the full leveling sets after leveling AST to 60.
Defensive cooldowns? Am I missing something? I can use Protect and Adlo (and in theory Stoneskin, but the casttime alone kind of disqualifies it to be cast in the middle of a fight), the tank usually never stays in Sacred Soil anyways (and using it also cripples my dps). Eye for an eye is useful about every third pull, unless it's not, because most monsters in the Aery have magic-based attacks which means even if it triggers, it does absolutely nothing. Eos would be useful against magic-based mobs, but then half of the party starts crying because they want Selene's buff. Don't get me wrong, I don't consider myself a good Scholar by any means, but I hardly see anything wrong with what I'm doing. Leaving it to the fairy is simply not an option.

Also saying that Lustrate is 'weak as hell' kind of discredits your opinion here. I'm pretty sure every healer who knows what that spell does will disagree with you on this.

It heals some HP. With a potency of 600. At most 3 times in a row (or 6, if you get new aetherflow stacks in between and do not need to use them on anything else). It's no magical save-all skill like Benediction or Essential Dignity that gains potency when the tank's HP get low. It's just a slightly weaker version of Cure/Benefic II, with the slight advantage of being instant cast (which Benefic II is pretty often, as well, so not really any gain). It doesn't even have the special traits anymore that it had in ARR that made it useful for situations where healing spells that rely on potency got useless due to anti-heal debuffs on the tank (like in the Ramuh fight). Now it's just a weaker healing spell. So please tell me "what that spell does"...

More on topic:
I really hate it when healers just laze about. As in, they heal if necessary but just don't do anything when there is no need to heal. But at least in my experience, on SCH there is just no time to dps, not because I want to be lazy but because otherwise my party dies. Which is the main reason why I'm always amazed by people writing about how SCH is 90% dps and 10% healer o.Ô
