It was post patch, and while the damage is only 57% physical, the shadow portion is based entirely off the amount of physical damage done. It won't double dip like it does with other modifiers, but it benefits from Hysteria (1.2 * the physical damage modifies the shadow damage by 1.2 in turn).
I also forgot why to mention why using Hysteria on warriors is largely a wasted measure. It won't stack with Wrecking Crew on Arms Warriors or Deathwish for Fury (so if you give it to a Fury Warrior, you need to coordinate).
While I looked that up, I found the list from patch 3.1 that describes somethings to consider when giving out Hysteria:
"
Hysteria,
Tricks of the Trade,
Enrage,
Wrecking Crew,
Death Wish,
Arcane Power,
Owlkin Frenzy,
Beast Within, and
Avenging Wrath damage bonuses no longer stack together."
