To get to your question specifically about catalysts, I imagine Fingerprints of the Gods will still exist, and if I were to make a guess, it'll probably be an ability that you can proc with GP. (Gathering Points) So while FotG was kind of an auto-proc ability before and you could gather x amount of catalysts in a row, you might have to sacrifice using your other GP abilities while gathering a node, since GP is a limited resource, if you want focus strictly on getting catalysts.
Hope that helps.
