Vs Bloodwhetting, Heart of Corundum, or Holy Shelltron that has a fixed duration that is actually up and running longer than TBN, costs absolutely nothing for Gunbreaker and Warrior to utilize and can also be used twice per minute, that mitigates damage and heals the user as well. ( And in Bloodwhetting's case, shields you as well )

Bluntly, yes, they are more powerful. And arguably far, far more useful. If a Dark Knight is holding back their mana to fuel TBN's constantly, they are sacrificing something they shouldn't have to.
Everything that Crater said there covers what I'm about to but I'll respond myself anyway. This is talking about dungeons. You're not losing anything by using TBN on cooldown in a pack of mobs. If you're using it once a minute in a dungeon mob pull I'm not envious of the healers that get you on DRK in their dungeons. No wonder people think DRK is weak in dungeons if people are sitting on it's most powerful tool.

Also the duration variance is completely irrelevant. What you're looking at is that it breaks at which point it's prevented 25 % of your max health of incoming damage. You could realistically get 3-4 uses where it breaks in any mob pull. With 3 you've effectively healed yourself for 75 or your heath. If you get a 4th then you're looking at a benedictions worth of shields. And this is something you can just keep doing on every single mob pull while combining it with your other mits.
