My own experience is that set items are as rare as before the patch, but uniques are very frequent (relative <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> ) <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> .
I have on my harddisc an Amazone with 4 or 5 unique items.
All of them got after the 1.10 Patch.
