Like many other DRK players I'm disappointed over the lack of love for our skillset.
I feel like DRKs are behind WAR and PLD, having tried them both up to compare. A fix I'd like to see would be more selfhealing...but PLD has the Spells, and WAR and DRK share the healing by hurting.

Suggestion: Using Dark Arts with defensive CDs gives us a Heal over Time. Make Shadow Wall the most effective would solve the problem we have with it not being up to par with the other tanks, but not just scaling the effect or CD.
Dark Mind would also see alot more use with a little healing thrown in.

Thats my suggestion, could it work? What makes it not work? Comments welcome.

(Also like other DRK i'd love to see better defensive CD, more bite to our Dark Passenger, faster locked animations, less need to keep the mana pool under a hawk/eagle/beholder eyes.(ect ect) But I'd like to see more focused discussions, as i hear those are more noticeable by the developers)
