LR5 for me is still more of the same only _slightly_ faster with the noise bug that I have described elsewhere. I have to do a LOT of editting and I shoot exclusively RAW.
I spend most of my time as a professional photographer in front of Lightroom. The horrible way LR4 and now LR5 reacts has really killed ot for me and I am struggling to find an alternative with as good workflow and output quality.
Its clear now that a suitable fix for this issue is not coming.
