Living Dead and other DRK QOL in 5.3

[Cyatheales]

The main problems I have with living dead are that it's (a) a needlessly complicated effect that's hard to track, and (b) too heavily reliant on your healers dumping all their powerful cds on you afterwards due to drk's lack of on-demand sustain.

How's this for a simplification of the effect?

Living Dead
- Instant cast, 300s recast
- Grants the effect of Living Dead for 10 seconds (or 8, or 12, or 14, whatever's balanced now that it's not "layered"). While under the effect of Living Dead, your health value may be reduced to negative values without it resulting in your death. If your health is at zero or lower when Living Dead expires, you are immediately killed. Certain attacks may still result in your death while under the effect of Living Dead. (referring to the usual invuln-resistant stuff like enrages)

And while we're on the topic of giving drk some burst healing, here's a random idea for a new skill:

Necrophagy
- Spell, 3y range
- 3000 mana
- Instant cast, 2.50s recast
- Deals unaspected damage with a potency of 200, and grants Feeding Frenzy for 5s.
- Additional effect: Restores an amount of own HP equal to damage dealt.
- Feeding Frenzy effect: Your next cast of Necrophagy has 300 Potency and costs only 2000 mana.

Since lack of sustain seems to be part of drk's job identity I wanted this to have a tradeoff, which in this case is the mana cost. If you use blood weapon with it you can use it 6 times in a row for a 1300 potency heal, slightly higher than warrior's Equilibrium.
