It would be nice if when you "proc" a perfect cut, you just get the rare quality cut. So a Perfect Delicate Pandarian Garnet would just be a Delicate Primordial.
That said, I agree that the AH UI is quite terrible, but it is quite easy to augment it. It would be great if auctionator was built in, but I'd rather Blizzard spent that time on new content, when I can spend 30 seconds to download an addon and have it anyway.
