Also in this first build are the first couple of chapters of the 7.3 storyline, and some new and improved casting animations for Restoration Druids, Elemental and Restoration Shaman, Discipline and Holy Priests, and all three Mage specializations (and yes, that includes Arcane Missiles). As with previous patches, player feedback is very important to us as we work to update these animations, so we’re really looking forward to hearing what you think.
(Note: Shadow Priest animation updates are also on the way for 7.3, but aren’t working yet in this build. In fact, some spells are likely to have no animations at all right now. That’s only temporary while we finish getting the new animations ready for PTR testing.)
