Beta notes: new racials, Mage, Priest and Shaman redesigns, and no Horde in Dalaran

Blizzard's notes for the 15 October beta build: every race's racial abilities change, wands and Auto Shot need you to stand still for half a second, and Horde players are attacked on sight in Dalaran. Mages get Frost Blast and a redesigned Arcane Blast, Priests and Shamans get moved and new talents, and Paladins get Salvation as its own spell with Revoke.
