i dont like festering wounds. the rest is ok.
I'm not a huge fan of the current form of Unholy from a PvP'er. I just don't think that Festering, nor, scourge strike does little DMG for the cost. Also, the wounds mechanic, while in raiding may seem neat, is not so much in M+ or PvP, IMHO. I don't care for it, but that's just me. Either Festering should apply 4 wounds, or do WAY more dmg.
