Should healing be this difficult while leveling?

[KDSilver]

Trying to level WHM myself, and this was something I was wondering myself. How you're supposed to use Asylum is a mystery to me. There's never really any pulls that have large AoE like that and the DD jobs only get hit with unavoidables or if they're stupid, so it really only would help the tank out, so I end up just not using it. You're really supposed to just not care that it doesn't help AoE cures and just use it as a regen for the tank? Seems strange, but I guess if I'm not using it for, well, anything it would make sense.

Also, uh, Cure II's a mistake? For me it seems like the tank's HP ping-pongs every pull outside of the first one. Maybe it's just Bardam's Mettle doing it's thing, maybe not, but sometimes it just doesn't seem like Cure spam + regen would be enough.

Cure II is not a mistake.My point was : ONLY spamming Cure II and ignoring the rest of your tool is a mistake ^^
Besides, is you feel like the damages are strong, of course, you'll prefer using Cure II over Cure. But what makes Cure a solid argument (at least at the very beginning of the pull) is that it costs less and can proc Cure II at free cost. Since the OP seemed to have mp issus, that's why I said that.

You don't need aoe situation to use Asyluym. Yes, it is aoe, but it can also be used as single target HoT. And the best example for that is dungeon where only the tank takes damages. Asylum is a free oGCD so it's better to use it.

One small note I've learned, Cure III's splash healing range doesn't seem to be very large. I remember on the last boss of Bardam's, I stood inside of the bird when everyone was still in the melee hitbox, cast Cure III on myself, and it hit no one. That suggests to me Cure III's not really useful outside of more organized raiding, unless I'm missing something.

Cure III range is the same as Asylyum if you want to have an idea.
Cure III is useful when you have to aoe, and everyone is at the range of your spell. It is indeed used more on Primals fight and raid.
One Cure III is less expensive than two Medica, and is faster to cast. That's what make it really good.
