Why do so many healers not use specific abilities?

When I read OP list, I was expecting like Largese, Lucid Dreaming, or Cleric Stance, not abilities engrained into their kits. I have no words, I'm just glad I'm not one of them...

Now, how do I faerie again?... lol.

I wish they didn't exist. xD But I've seen them too often unfortunately.

The thing is, using Divine Bension and such really clips into your GCD if you're not using it after Aero.

But in a situation where you would need Divine Benison for a tankbuster, wouldn't it be better to clip into your GCD because you would have to heal less then? I'm quite casual but I feel I have to heal much less and can dps more if I use Divine Benison. I understand that in a 100% planned out rotation in a perfect group you may not need it maybe, but at least in normal farm content with random players it's a great ability that seems worth clipping into your GCD. (I've given up on trying not to clip into my GCD as WHM anyway though. If I tried it I wouldn't be able to use 80% of my oGCDs when they are necessary. But as I said, I'm more of a casual player anyway.)



Besides, what I actually wanted to say with this thread was not "which healing abilities do you sometimes forget to use?". I mean, I'm guilty of not using Eye for an Eye as often as I should. Sometimes I forget about Cleric Stance when it's already up again too and so on.
It's about healers who don't use abilities like Asylum, Divine Benison or Excogitation AT ALL or only like once or twice during a fight where it's needed or really useful, like extreme trials or savage raids.
I've seen those kind of healers so often now that I'm just tired of it and wanted to know if others have noticed the same... phenomenon. And what they think about it.
