I would actually beg to differ on NYU Wagner not having a student community, of sorts. While the lack of true "campus" and such may ring true for the larger NYU community/undergrad life, NYU Wagner struck me as very cohesive and interested in the wellbeing of their students. NYU Wagner students I spoke to seemed to be very close with their fellow classmates, and often go to happy hours and networking events with students at Wagner and other NYU schools such as Stern and GSAS. As for the quant material, it seems up to the student to decide how much quant they want to take--Wagner does have a Finance Specialization that seems just as quant heavy as any standard Finance/Management specialization would/should be, but if you were to veer away from the Finance/Management courses I can see how the curriculum would end up less quant-focused. YMMV.
