I just don't understand how they keep saying things like "We're listening to your ideas!! We really are!" and then flat out say no. We don't know what's in store for us for the expansion and we won't know for a bit. In the footage we saw, the old models were being used. That being said, I didn't notice any other classes using new abilities. It's possible they just didn't want to spoil some kind of reveal. Only time will tell.
