As for resto, yeh, they do feel a bit underwhelming. Still no cool iconic NEW spell, still the same cast-based crap(which will hopefully be less bad in cata), still no oh-sheit button, just a few I-do-this-and-then-my-next-heal-is-20/25%-stronger and lol-I-cast-2.5sec-lightning-bolts-for-mana. For PVP then.. Most importantly we lost cleansing and the total ability to cleanse poisons which will hurt our defense pretty badly.
