Ra's willingness to adapt the offensive strategy of The League of Shadows to match the unique fissure points in Gotham's culture - her profound susceptibility to criminal influence; blurred/polluted lines in enforcement of law/ethical mores; sophisticated comprehension of the relationship between economic vulnerability and emotional weakness ("Create enough hunger and everyone becomes a criminal...") speaks clearly to an individual able to accurately convert broad sociocultural pattern into a singular plan of action. As you know, powerful Ni is the ability to concisely forecast data cultivated from what might otherwise be understood as "white noise".
I see your connection to Ra's dedication to tradition. Tradition, I suspect, is of secondary importance to his ultimate goal of eradicating unsavory elements within the human condition that prevent us from "confronting truth" (See: The Will to Act segment)
He is fundamentally an abstract thinker. Tradition is simply his instrument of choice in furthering his essential desire to reduce psychological dependence on "untruths".
He is willpower, given human form. To this end, Wayne's intense focus is offered perhaps as a consequence of Ra's.
