Blizzard's Wrath talent trees page has been updated with minor changes, such as new icons for Wrath talents, as well as major changes such as a long-clamored for polish to the Mage trees. A noticeable change, for example, is the removal of Spirit from the equation for the Arcane tree. Potent Spirit and Student of the Mind, Spirit-based talents, were removed to make way for Arcane Flows and a reworked Netherwind Presence. The former reduces the cooldown on Arcane Power, Presence of Mind, and Invisibility by 30 seconds, while the latter now grants a passive 6% spell haste at max rank.
Most changes are cosmetic -- the humorous placeholder icon used on many of the game's spells in development have been removed -- although astute players may find updates to the wordings of talents across the board. Other changes include some talents buffed and reduced in talent points such as the Paladin talent Vindication (down to 2 talent points, from 3; buffed to 20% from 15%). Check out Wowhead's talent calculators, which haven't been updated as of this writing, for comparison.
