I agree that wisdom should remain the prime requisite of a cleric-type, otherwise it ends up being just for will saves and skill checks and might as well be merged with Int. The small element of MAD introduced with turning being Cha dependent and spellcasting Wis gives a little balance to the Cleric as is. I liked the way that 2e priests had spells strongly tied to their deity, and this seems to reinstate that nicely.
