The problem is when dealing with 100s of images that extra 10 min can't happen. I guess if there is one exceptional frame then maybe. Even NR in Define 2.0 takes too much time over applying it in LR. It's the same for correcting for the cycling lights. Each image is unique and requires extra time to process. It's not that it can't be done but that it's not practical with many photos.
Quite. Everyone's needs and workflow is different. When composing a wedding album for instance, it's not about 100's of images (maybe 50~80 tops) and there will only be like 5 or 10 needing extra care. That is very feasible and that is what I meant when I said "emergencies". If, like you, it's about a whole bunch then yes I agree, it can't be done. Many noise removal software packages feature batch processing, but usually that won't do because you'll need to exclude the subject in focus from the NR layer.
Oh well.....it's nice to have for incidental "emergencies". I could not do it with my 5D, as it ends @ISO3200. This is a substantial feature of the 5DmkII.
