I've just noticed when I checked Stars' feral tank after his Anub'Arak HC kill that he is using Blood Draining. Then on the other day, I saw another top end raiding feral tank with that enchant. What is this new trend? Did Blizz changed Blood Draining to heal % of own HP, or is it still a flat amount of heal/stack? If the second option, why does it even worth it? I don't get it, halp.
