Yes yes I know. "But WHM is the RAW healer".
Damage is getting stronger and stronger with each patch. Shinryu is quite literally impossible without loads of help from the tanks, the 24man raid even do ridiculous damage without mitigation.
It's to the point where tanks are mitigating the party more than we are, which is actually pretty sad. A warrior mitigating the party more than a WHM. That is, by all means, a ridiculous thing to say. But it's true.
It doesn't have to be strong, just a little something for the few times we run into double WHM and have no answer to the excessively high damage we've been getting lately. Right now WHM is the only healer that simply sits still not doing anything useful In the face of damage that could potentially wipe your party, and it's a bit sad.
