The mind boggles at the notion that a class that 'never actually learns to cast spells' would count as a 'spellcasting class.' Then again it is WotC we are talking about so I really shouldn't be surprised anymore. Losing the adept casting isn't much of a loss, as I was really only using that to further qualify that you know the Mother Cyst spells thanks to the Spell Mastery reference. Knowing the spells was only important for Desert Insight and Unseen Seer portions. The Desert Insight trick has already been shown not to work. I suppose Unseen Seer should probably be ruled out now too.
