from the patchnotes:

- Soul of the Crafter
Players can hold up to three specialized souls. You will need to relinquish one of your three specialized souls if you wish to specialize in a different discipline.
* Players will receive three souls of the crafter upon unlocking the crafting specialist system, which are required to receive a specialized soul. However, players will be unable to obtain additional souls of the crafter until a future update.
Does this mean we cant change our specialization? :/
