What about creating an ACTUAL Dark Knight?

I'm no tank expert, but couldn't they combat the issue with living /walking dead, by it giving a huge buff to healing until the checkpoint has been met? I.e a Regen could comfortably bring the Drk back to full health within a couple of ticks. Obviously, there would be a balance issue with this which I am not even going to stick my toe in.

How the skill works atm is you just need to be healed for your full HP, not actually have your HP reach full. It works like WAR where your HP during the buff period can not be brought below 1hp. The first issue a lot of people have is the activation method. All other tanks just push a button and something happens, PLD gets inv for 8 seconds, WAR chains itself to the target and can't be brought below 1hp, GNB drops to 1 HP but is inv for 8 seconds, DRK has to die.

So right off the bat it's activation method is the worse of the 4. Now you have to consider what happens after you hit the button: PLD just loses it's inv, WAR unchains and is at w/e HP they are at at the time, GNB loses inv, DRK if it does not achieve the healed for max hp caveat DIES

If they gave you a buff like let's say Condolence's incoming healing increased while in LD then you could get out of it faster yeah, but the skill is not good on a fundamental level especially compared to the other inv skills
