“Increased the potency of several actions to make WHM in line with other healers”

[Exiled_Tonberry]

WHM is the best at actually healing... But SE refuses to make that relevant.

Even then it's not, Sage despite being a barrier healer and AST handles situations way better than WHM could ever dream to.
Now if you're talking about sitting down and spamming Cure III then you have a point, but not even Ultimate requires that, and when content does require that much healing they'll just buff the other healers to match the need instead of letting WHM shine for once.
