As DRKoftheAzure said TBN is not free! Its mitigation is for real, but the risk of losing 500 pot/300 pot per target still exists. And as we know if you lose damage dealt, the target(s) live longer, you'll take more dmg, and need more mitigation. Then TBN would've failed its purpose.
Now, Ultimates are really close to said vacuum: TBN breaks for roughly 90% of time if used on CD. Just a little tweaking to the timing, and it will break 99% while greatly mitigating damage. All other content (and yes, even dungeons) this %-chance just drops significantly. I've seen 3-4 mobs NOT breaking the damn shield multiple times despite full duration usage, bosses sometimes don't even tickle it.
If not used on CD TBN loses value. e.g. WAR heals roughly 50k HP every 30s with Nascent Flash. TBN shields you for ~37.5k HP every 15s. In theory TBN "heals" more than NF, but because we cannot or should not use it on CD at the risk of not breaking it. Reduced to practice, this means TBN gets weaker than its equivalents. (I am aware ofc, when you overheal with NF it loses value, too.)
If you need it to survive, and it breaks, it's the best mitigation ability. Otherwise it becomes mediocre, or even a loss (sadly).
TBN is an ability that requires skill for efficent use, it still bugs me that it comes with (the highest) risk contrary to its equivalents.
