If I were to check off SARowl's list for the S-92, I would find most items quite nicely met, including downwash. Recent work by the USAF in evaluations found that the hoist/door was excellent, and litters and people were easily hoisted with the system.
Change is never easy, but when we set concrete, we stifle innovation. The S-92 is a far safer and better helicopter than the lovely, venerable S-61, just as my 2003 car does so many things so much better than my old 1963 Chevy did.
Nostalgia is not a design constraint.
