I think WHM is well overdue Reposega... I mean every other job that has sleep spells has some aoe version (with exception of rdm if not /sch.. but then again rdm is heavily single-target spells anyway) BLM, SCH (accession), BRD and even BLU....

While they are at it, WHM should get Banish IV and Banishga III.

A cool idea could for pld to have a "Summon Holy Servant/Spirit" which deals DoT damage but the hate goes towards the pld itself. Would fit into divine magic skill quite easily. The way I imagine it is more like a decoy rather than a SMN spirit but I'm guessing it wouldnt fit in with SE'd ideas of a pld in this game
