1) Should I even bother keeping Sustain on a hotbar as a Scholar? Unlike Arcanist or Summoner, my fairies are never going to be engaging enemies directly, so the only source of damage they should be receiving is from AoE attacks (correct me if I'm wrong), and since fairies have barely half the amount of HP as a Carbuncle, it seems like Sustain would be a very poor method of healing any damage they manage to take when I could just hit them with a more powerful Physick for the same MP cost and GCD. What I'm saying is, if I'm hard up for convenient hotbar space, would I be gimping myself if I left Sustain out?
2) Is there any time when I would ever want to use Miasma II? I'm looking at it and thinking why I would ever bother. It has the same initial potency as Miasma (20), does less damage per tick than Miasma (10 vs 35), has a shorter duration (15s vs 24s), identical Symptom effects and costs more MP to cast (53 vs 38). The only thing it has going for it is that it's an instant cast and it affects all targets in a 5y radius. The former doesn't really seem to matter much since it still has the same GCD, and the later is rendered moot by Bane. Help me understand when/why I should use it, because I'm struggling to find a reason.
3) Has there been any word on when Obey/Sic might be fixed so that it no longer requires a nearby enemy target and doesn't root my fairy in place for some reason? I would love to take manual control of my fairies' abilities, but it's like SE has intentionally arrayed obstacles in the way of doing so. Every macro suggestion I've seen to get around the annoyances are easily broken, potentially just making things worse.
