I'm not the biggest fan of the building design... however, if the height of this thing gets chopped, I will be extremely disappointed in the lack of foresight by the NYC city council.
In fact, I think this thing should be allowed to go higher, and required to construct a "iconic spire" the complements the Empire State Building and the Chrysler Building. Maybe bad example, but something along the lines of Chicago's Skyneedle proposal.
