What if we changed the way cures were scaled?

[Zojha]

Got anything better than "no u"?

Fine, I'll bite: Specialized healers are sill better at healing than some random guy with a physick spell, even if that physick spell was stronger than a regular healer's physick/cure. They are more diversified and have dedicated cooldowns for dire situations.

This is why dedicated DPS can exist alongside Tank and Healer DPS and why DPS checks are, in fact, needed everywhere, regardless of what people like.

As such, there is no harm in giving everyone access to a decently scaled healing spell. And that's not even the scope of the suggestion in the OP since heal spells for cross class are limited among jobs and you'd only give a handful of jobs access to one.
