I wouldn't really touch TBN, of all things, aside from maybe making it similar to what was defined as the Excogitation treatment or a partial MP restore to reduce the punishment. But TBN is, right now, the most important and powerful skill of the DRK - and the reason I like it so much is that it has a short CD, meaning its use is flexible, and I can use it to save others too and contributing to reducing damage on the main tank while still dishing damage. It's the one thing that no one has, why would you give THIS up?

The real issue with DRK isn't TBN, as I keep saying in these topics, is the fact that outside of TBN your CDs are quite lackluster. Also, the Living Dead issue. I wonder if it'd be possible if Living Dead was removed and Living Shadow reworked, and Living Shadow was the actual invulnerability instead of taking the Blood Gauge resource. Well, assuming they would remove the time it takes for the shadow to manifest - otherwise it'd be quite laughable. I like Living Dead's concept of going beyond your limits out of sheer defiance towards the enemy, and paying the price, but as things are right now it can't work without discomfort. DRKs similarly to GNBs have the worst kit to self-regen, so why they would make it the only class that requires a healing spike to survive is beyond me. At least GNB doesn't instantly die. Maybe another kind of punishment for using it could be dealt in the form of a reduced HP pool for a while, similarly to how the weakness debuff worked previously. It still is a big deal, but at least it's not a healer's nightmare/a death sentence for the tank.
