When World of Warcraft is updated to v7.3 in a couple weeks, caster characters of all races will be getting a whole new look...well, except for Warlocks for the time being. The community site has been updated with a couple of neat videos showing off the new animations as well as providing some developer insight into the hows and whys of the changes.
All Priest and Mage specs will be updated as well as both Restoration and Elemental Shamans and a few tweaks to Restoration Druids. Other classes (poor 'Locks...) and specs will be updated over time but not in time for v7.3.
Players can look for big improvements in "caster ready", "hand casting" and in the spell effects themselves. From what we've seen, however, there still is no casting animation while holding a weapon or staff. Hopefully that will also be something coming down the road.
The caster animations are a nice addition to the revamped melee animations that were added earlier this year.
