This is about the change to RPPM trinkets not having guaranteed procs on the pull right? That one basically makes Soul Cap useless in conjunction with the ring; I'd assume any others are equally as nuked.
The SoO trinkets still worked 91+, the effectiveness just diminished greatly as you leveled up. My hunter was still getting some cooldown reduction at 93 until I replaced it leveling up the other day. I do miss 7 seconds between Disengages though. I do remember the CDR trinkets being bugged at WoD launch and granting basically nothing, but that seems to have been fixed at some point.
