Miscellaneous: Proc levels

[Puyen]

I have noticed at least from what I can remember that some Proc levels seem to be higher then before. Easiest known case for me is the Serrated bone dirk. My first character back in the day was a rogue and I used 2 of these that proc'd under lvl 22. But also back then the weapon Proc level was not listed on the weapon description.

Does anyone else recall any items like that ?
