It's time to kill the argument that DPS abilities keep healers from healing.

[Sebazy]

Blame elitist stuff like parsing/the balance etc for making it that if your dps isn’t really high as a healer you are trash mentality

Oh no you don't

You can blame the various savage turns that either flat out required healer DPS to clear or at least strongly encouraged it to skip key mechanics and phases.

Then like so many other things this mentality was taken and applied to content in which it frankly didn't matter.
