Was it Defenders of the Wild that was godawful, then? I don't think it's Tome and Blood.
Can we all agree that Complete Divine was a book full of terrible, terrible ideas?
Ah!
Tome of Magic. Tome of bloody Magic. I will never forgive that book for promising me not one, not two, but three REALLY AWESOME sets of character concepts then being designed in such a way that none of them, y'know, worked.
Hells no we can't agree that Complete Divine was bad.
It gave us Favoured Soul, Shujgenjas, Spirit Shamans, Divine Cruasaders, Geomancers, Holy Liberators, most of which I'd love to see reborn as subclasses in 5e. It was one of the best books of 3.5e.
