those updates are from June, after the 3.2 patch
So thats interesting it looks like amp on other chars is
not bugged, just the cursed procs for bound demon warlocks since its using monster amp instead of necro amp. So yeah bone break on a bowazon not nearly as good, would still take a 100% dr mob from 95 to -5 instead of 80 though in that case.
Im thought the PTR initial patchlog had something about fixing blood oath before the final release dropped that line. Otherwise we did know about the borked +damage on bind demon right away since its right on the tooltip
