Dark knight is in an unfortunate position as it stands being the weakest damage dealer of the tanks, being too close to Warrior in terms of playstyle for many, very poor aoe damage, living dead requiring a healer and having a monotonous rotation of 1-2-3
Here's some ideas to fix some of these issues
Shadowskin- replaces rampart
If ranged can keep unique looking but identical abilities, why can't tanks? Bring back shadowskin
Syphon strike
Combo potency upped to 350 (previously 300)
Mp restored upped to 800
Souleater
Combo Potency upped to 500 (previously 400)
Cure potency upped to 320
Stalwart soul
Potency upped to 210
Living dead
Living dead status remains the same
Walking dead: While under the effect of Walking Dead, most attacks will not lower your HP below 1. If, before the Walking Dead timer runs out, Healing received equals to 75% of your max hp, the effect will fade. If 75% is not restored, you will be reduced to 1hp
Bloodspiller
Potency upped to 640(previously 600)
Quietus
Potency upped to 280(was 210)
Living Shadow
Timer now only takes effect when Simulacrum is able to attack
New combo
Scourge>Delirium>Power slash
All use their original animations from HW

Additional effect: Deals damage overtime potency 40, duration 30 (550 total)
Delirium

Sole Survivor

Recast: 120 seconds
When Sole Survivor hits target marked with Another victim with a skill or ability, a cure with potency 300 is received

Level changes
Edge of darkness>level 30
Flood of darkness>level 40
Stalwart soul>level 38
Shadow wall>level 36

-------------------
CurrentInner releasedelirium was deleted. The new combo is designed to replace it via two dots. The combo is more frequent being once every 30 seconds to replace the 90s recast.
The idea for the rotation being power>souleater>souleater>power>souleater>souleater etc
Living dead changed so its still possible to die if you aren't healed via autoattack or roomwide, but at least you have a good chance of mitigating it solo via TBN and use of sole survivor/abyssal/souleater
levelling changes were designed to plug gaps in the levelling kit, match up with other tanks and where possible, preserve the feel of the original job quest (such as sole survivor coming right at the end of the vault...)
