My biggest disappointment in Cata has been the removal of Resto having a form. It is a defining characteristic of the class, and we became the red headed step child of the class for all of Cata. Cats and bears got an awesome make over and we got... tauren/NE/etc form.
Yeah, I've enjoyed the cool down, but I never get to fully enjoy the shape-shift aspect. Typically you utilize the CD when healing gets more intensive- so there is no time to fully enjoy the fact that I am shape-shifted.
