In an official question and answer session, Blizzard thoroughly outlined dual talent specialization, an update that is coming soon to World of Warcraft.
To be included in the next patch, dual talent speccing will allow players to easily switch between two different talent specs, glyph and hotbar setups. Level 80 characters will be able to gain the ability by paying a one-time training fee.
Once gained, the talent specs can be switched at any Lexicons of Power. These lexicons will be available in major in-game cities; inscribers will be able to create an item that summons one.
“We will be launching the feature with just two specs, but depending on how we feel it works out, we might consider additional specs in the future,” said Warcraft senior designer Greg Street.
