This is the main reason I call DRK the worst tank. While DRK has all other problems that make it less fun to play with. Living dead is the reason DRK fail as a tank. It is a pain for healer to deal with correctly. First I need to make sure DRK lose all hp to trigger walking dead and then within 10s I need to make sure his hp is heal back 100% or he dies. In a perfect world where I have all the available oGCD heals this is no problem. How about during tight situation? For example in Shinryu ex, dancing between aoes and that super tank buster ahk morn and tera slash while all I have left is the GCD heal. All I have is frustration thinking why couldn't you be like HG or HmG where I actually have time to heal tank to a stable amount of hp because it actually mitigates the damage, then move on to heal rest of the party instead of praying you to not be dead while spamming the heal button. Whenever I see the macro "Living Dead is on" I just focus heal the hell out the DRK to not let walking dead happen because I simply don't want to deal with it even in 4-man dungeons.

The different between DRK and the other two is hell and heaven. While DRK here screaming heal me please, WAR and PLD over there simply says, "yo I got this, healers" with a confident simile.

In contents where tanks actually need to manage mitigation, I simply hate DRK.
