Massive drop in DClone Spawns

Has anyone else noticed that Dclone is hardly spawning anymore. Up until about a month or two ago it was common to have him spawn multiple times a day on the Asia server but now it seems to be over a week between spawns. Is anyone aware of any changes that Blizzard made to reduce the DClone spawn rate? Or maybe did they crack down on people duping SOJ's. Just wondering if anyone knows anything or if anyone else even noticed.

Yep, there was one sudden walk two hours ago in Asia (went from 4 to 6). But now it is the same since ladder reset. I watched the Walks for several weeks now and posteted my findings here

I still have ca. 70-80 unid annis in my stash. Maybe I should keep them and hope prices will go up further
