From my observations, Eu SC NL walks about once a week, NA about once a day and Asia several times a day. I basically no longer chase the Eu walks.
Are you switching regions to try to catch Diablo Clone? It easily done if you see a region at 5/6 (but for Asia you have to be REALLY fast sometimes, so I recommend switching at 4/6 if nothing else is happening).
