A lot of gear will no longer have +AP on it. Such gear will be converted to +Agility, so the incentive for Fury warriors to 'downgrade' is gone (less attack power and you lose your armor bonus).
Spirit is still in there, but mp5 is gone. Not only that but spirit also increases the hit rating of Elemental Shamans and Balance druids through talents. I recall warlocks and mages will no longer find spirit on their gear however.
