Issue with TBN

[DJMau]

Y'all are missing the point. TBN does not give you a reward. On the contrary, it comes with high costs! It is not free, far away from it.

You want to see a free ability? Go to GNB and use Heart of Stone, go to WAR and use Raw Intuition. There, free mitigation!

Everytime you use TBN you pray that the shield will pop. And don't get me wrong, the shield is strong, it is great. A cooldown giving a strong shield is a unique and good design to a tank. The problem lies in DRK toolkit that makes the design bad as a whole. It's costs being tied to your damage!
It shouldn't cost damage, because you'll refrain from using it. And right now it's not used for fluff mitigation, or you rely on rng that the shield gets registered right before the next AA, and you get hit hard enough to break it. As for the other tanks you can, will and should use Sheltron/HoS/RawI for fluff damage, overwise it's wasted mitigation.
On the other hand you can't make it give you additional damage, or it would break the job. The skill ceiling would be too high.
If DRK had any other ability in its toolkit for fluff damage, using TBN for tank busters only wouldn't be such an issue.

In certain fights it would remain as a niche ability. e.g. most recent duty E3 Leviathan: this boss mainly uses AA and mediocre raid-wide damage mechanics with just 2-3 high damage tank mechanics throught the fight. (Actually found a log where a DRK uses TBN only 4 times in 10 min!)

For all those who claim that DRK does mitigate tank busters better than any other tank CDs: That doesn't matter. The amount of times where TBN will save you over HoS or Sheltron will be so minuscule, almost non-existent, probably near <1%. The amount of HP you save with TBN over the other tanks' CDs is not relevant! It will not save a heal, neither will it increase the healers DPS for the cost of yours'!

TBN staying an ability with high risk, no reward is bad, and should be changed.

I've seen this line of argument before...oh yeah. Xeno's exact argument against TBN.
