DRK doesn't need a buff or a nerf, it really needs a massive rework to be more synergized with the rest of the jobs.

for instance:
1. They really need drain skills or the ability to heal themselves (im looking at you pvp buff) so they are not an extreme burden on the healers. Too many times i said really wished i played PLD.
2. Reduce their initial burst dps but increase their sustained dps so they don't fall completely flat.
3. Living Dead can straight go to hell with its debuff that just kills you if the healer fails by 1% (you should not be killed if you have at least 50% hp)
4. Living Shadow should COMPELETLY mimic your abilities (with reduced damage)
5. Niche skills (dark missionary, dark mind) really should give mana if hit by a magic attack as blood weapon doesn't really last long enough and Delirium gives too little and adds more counter options besides TBN.
