I'll have more about the class changes later... but I just read this in the Priest changes and near soiled myself from laughter:

Leap of Faith (level 85): Pull a party or raid member to your location. Leap of Faith (or "Life Grip") is intended to give priests a tool to help rescue fellow players who have pulled aggro, are being focused on in PvP, or just can't seem to get out of the fire in time. Instant. 30-yard range. 45-second cooldown.


EDIT:

Warrior preview is up... have so say I glanced over it and I found THIS to be wholly entertaining and a long time coming:

Overall, heals cast by players in Cataclysm will be a lower number relative to players' health than the current game. So to make the Mortal Strike debuff less mandatory but still useful in PvP, Mortal Strike will reduce healing by only 20%. All equivalent debuffs, including the Shadow priest and Frost mage debuffs, will be for 20% less healing. At the moment we aren't considering giving this debuff to anyone else, though we will certainly consider PvP utility for historically under-represented specs that use other mechanics.
