First time really posting in the official forums, but here goes:
I think that Dark Knight's (DRK) Living Dead should be changed as follows:
----------
Living Dead (Lvl 50)
Call upon forbidden magicks to forestall your end, preventing most attacks from reducing your HP to less than 1.
Duration: 8s.
Cooldown: 300s.
-----------
And a new trait at lvl 62 [or to add to Blackblood or Enhanced Blackblood (level 66) :]
-----------
Enhanced Living Dead (Level 62):
Living Dead's duration is increased to 10s gains the effect:
Exchange your current Blackblood and HP amounts, while also granting 5 Blackblood for each physical attack landed.
When Living Dead expires, exchange your Blackblood and HP values again.
If your current Blackblood is at 0 at the moment of exchange, you will have 1 HP.
Blackblood formula:
1 Blackblood = 1% HP
HP exchanged with Blackblood will be converted to a percentage amount equaling the percentage of your total health, rounded up.
Duration: 10s. [Cooldown will remain at 300s]
{Something to consider: Allow the Dark Knight to activate Living Dead again to end this ability early after 1s-2s buffer Cooldown}
---------
So why change Living Dead's effect? In my opinion, Living Dead is the weakest out of all the tank immunities. The Dark Knight that uses Living Dead has now way to continue battle by themselves once they enter their Walking Dead effect. Dark Knights do not possess enough curing skills (A 60s Abyssal Drain, a 3rd GCD Weaponskill: Souleater) to heal an amount equaling their HP total, and if there are no healers around, Dark Knights can only wait for their end.
This gives Dark Knights a chance to continue on by themselves, to bring their immunity in line with the other abilities, Such as: Holmgang; Hallowed Ground; and Superbolide.
Some balancing that I can already see happening to my proposed Living Dead:
-Duration may be too long
-Blackblood granted per physical attack landed my be too high, may be lowered or changed to 'per weaponskill' instead.
I do hope that this proposal is considered, but I would also like to invite the community (and or Devs) to discuss this ability.
