As the title says, what are signature ability decks? Are they just the talents most commonly associated with a given career, culled from various specialization decks?
What are signature ability decks?
Not having seen one, myself, I’d imagine they’re similar to the specialization decks, but for the signature abilities.
Where the specialization decks give you cards for each of the Talent boxes in the spec, allowing you to maintain a deck of what talents you have (and how many of the ranks in the ranked), the signature decks probably do the same for the signature ability nodes.
Signature abilities are the 30 point talents found in most splat books. I would assume that signature ability decks are like the specialization decks, only with the signature ability trees.
