I don’t think my response warrants that sort of reaction, but if I offended you I apologize.
My four year program was four years of design, there was in fact no humanities involved, and based on my experience, I couldn’t imagine cutting it a year short, especially coming from no design background. My campus was also shared with our 3 year Master’s program, so my opinion comes from what I saw and is only to contribute to the “discussion” and help the original poster in making an informed decision.
