The WoW Cata Classic API for retrieving any character’s specialization data seems to have stopped updating. Attempting to retrieve any character’s info simply returns the data from before the MoP pre-patch, including the talents that now no longer exist. People whom have changed specs are still shown as having their old specs.
As a result, any Monk will not have any specialization data, as these characters did not exist prior to the prepatch.
In short, it is now impossible to determine one’s specializations.
