Living Dead is often an unfun and frustrating cooldown for both tanks and healers

Compare this to Holmgang and Superbolide...

Superbolide is flawed too.
It reduces you to 1 HP a fraction of a second before it makes you invulnerable.
I learned this the hard way last night in Dohn Mehg, as I hit Superbolide with enough HP to survive a couple seconds (but the healer was down so...) and just died, instantly.
