Counterpoint, though, a tank that can realistically sustain with a downed healer is going to be required for any content that matters. If the class can't sustain without a constant supply of external healing, then there's really no point in allocating so many skill slots on self-heals when they could be using mitigation instead.
I was thinking about my previous post, and I realized that making this kind of change still doesn't make Living Dead any good. You're not going to get enough healing from it to make it worthwhile on single target (read: boss fights), because the rate of incoming damage is relatively low compared to the strength of each hit. It's the same problem Blood Price has, it's amazing on trash pulls but kind of "eh" when you get to the bosses.
