Are we talking about patch 2.3.2? The one that's on the PTR right now? If so, is this hemo nerf an unannounced nerfing because according to the release notes
here the only change to Hemo is:
Hemorrhage: Rank 4 of this ability no longer has its charges consumed by non-physical attacks and spells.
I see nothing about a damage reduction. The only place I ever saw that mentioned was on the o-boards - while they are hosted by Blizzard they're hardly an official source of information.
Or has someone been on the PTR and seen the debuff? If so I might try a muti/subtle build.
