Dark knight really lost its identity in SB, most of its skills either got deleted or put into the role skills, the dark arts spam is ridiculous, for every skill you need to use dark arts to maximise dps and if you compare the damage output from warrior to drk, war is so much more powerful and easier to play.

Drk also lacks the raid utility and defensive cooldowns of a paladin, there's also no self heal when not in tank stance while the other jobs have reliable self heals no matter what the situation, sole survivor isn't exactly reliable.

Living dead should also be changed, its so much weaker than the HG or holmgang in that it requires assistance from another person for it to actually be useful. While holmgang could use assistance its on a really short cooldown and has other benefits to it, but due to the self heal war has it is actually pretty safe to use.
