What changes will push sch out of meta

Their healing kit is fine, it's just that only having 'large heals' as the class' identity isn't very useful when a lot of the content does not or cannot require that much raw healing power.

It's more than just that. The other healers aren't really behind on healing power. 2x lightspeed helios is just as good as Cure III at equivalent MP cost. Actually, 2x helios slightly more healing, and with no cast time you can have 2 of them as the first cure III goes off. This is before you factor in AST stance bonuses.

And there's nothing so tightly timed you need to have to healed within a single GCD anyways, unless you're trying to cheese/ignore tank swap mechanics... which again, you don't need a WHM to do even still.

People talk about WHM like it's the king of raw heals but it's not anymore. It hasn't been for a long time. And that's a big part of the problem. Even the 'one' thing WHM is supposed to do well, it's outclassed in. You can add content that requires insane amounts of healing, and AST will still be the better raw throughput healer.
