I'm not an expert by no means. I have PLD to 50 but been playing DRK since Heavensward.
What i can say is a bit inconsequential but i would really like to stress how much i love living dead skill
There are some very few fights when you pop living dead just to gain those couple of seconds, with a dead healer, that the group requires to down boss.
Shortly after you die.. like some epic warrior having fulfilled his ultimate purpose.

Yeah i know.. it's not exactly a reason to choose a class over another
