Some one please correct me if I am wrong. I remember reading somewhere that the higher the item level of the RPM trinket, the more freq the chance of proc. IE the 522 feather will not proc as much as the 535 version. Did I miss read a post?
This is only true for trinkets that have a static effect, e.g. Rune of Reorigination and Unerring Visions of Lei Shen. The RPPM chance doesn't change at all for any trinkets warriors use, because the strength of their procs scale already.
