There is one aspect of WHM that I do not like and this would be Plenary Indulgence.

I find it to be too random and not have any specific relevance in relation to the actual mechanics of the class.

Plenary Indulgence needs to be re-worked in some fashion although I would have to see what it is like in raiding scenarios.

I said it in the WHM thread as a suggested change but something like a link to the actual Lilly mechanic where there is an extended duration of the plenary Indulgence buff based on how many lillys you have or something along those lines.

The other option is just to make plenary indulgence work with the Lilly Mechanic and having the heal based on a number of lillys you have.

I will give it the positive aspect of the actual heal is that it does not invoke the GCD giving you an extra heal.

An additional change that could be considered is adding a chance to Divine Benison that would cast a shield on the WHM it is a bit of an RNG wall which I am complaining about with the Plenary Indulgence but then again it would work with the mechanics that are given to us.

You could even instead of the WHM give it a chance to cast the shield on a party member with the lowest HP.

The cooldown reduction on Assize and Tetragrammaton are a welcome change.

The boost on Cure Potency is actually really good and the MP Management of WHM is a lot better.
