I've been playing a bit in Beta and one of the many things I have noticed which could have a large impact on how people play is the new ultra rare gear. These pieces have the same stats as their raid dropped equivalent with a different graphic and name. They are also can be attuned as opposed to no drop like the raid pieces. Right now they have listed one piece for each raid non-visible, weapon, and shield. Not sure if this will go live but it is this way in beta.
