The short version is that TBN + Oblation is about equal to the other Short CDs on busters, and only busters, and only then if we discount the healing put on them.
TBN + Oblation = 125% HP / .9 = ~138% EHP
Bloodwhetting = 100% HP / .81 * 1.072 = ~132% EHP
Heart of Corundrum = 100% HP / .72 = ~ 138% EHP
Shelltron = 100% / .8 / .85 = ~147% EHP
Moving into other scenarios, TBN + Oblation begins to fare worse almost entirely because it's the only one of the combinations that doesn't restore health, in addition to the actual % mitigation being lower. Once the shield is gone, which in a wall to wall pull currently would pop the shield and then all you have is a 10% mitigation.
Comparatively speaking, the other tanks still have 15-25% mitigation running, and their "TBN" worth of health is still coming in. While theoretically this means all the tanks are mostly equal in this regard, the reality is that Dark Knights require more support and awareness in staying alive. It's just a matter of numbers at that point, though experienced Dark Knights with experienced healers will hardly run into any bumps. This in part is also contributed to by Living Dead still being a trashfire. That's 10 seconds worth of cooldown reduction Dark Knights are conditioned to avoid using in most cases.
The short version here is that the enemy scaling Bloodwhetting and Nascent have should probably be removed, and then things stop at least being absurdly ridiculous. Finally fix Living Dead in addition to that and maybe the riot will stave off a few more months.
