I would have chosen Columbia, NYU, or Chicago over Harvard had this travesty been enacted before I attended law school. (I refer to the focus on international law, not the mock-litigation format, which sounds like an interesting idea. However, the two changes in tandem are absurd; HLS already teaches the law of no particular place in a vague way; soon it will teach the law of a vaguer area in a more specific manner. Hmph.)
Arthur Miller already left HLS in a huff when they changed Civ Pro from a two-semester class to a single semester. Even if he went along with the faculty vote, I can't imagine he's pleased at the prospect of reducing Civ Pro's class hours.
