Is TBN a bad skill?

[Kabooa]

Something can be powerful and still be bad - It's about comparing it to its contemporaries.

Objectively, TBN is the absolute strongest short CD Tanking cooldown. It is +25% of Maximum EHP, period, for 7 seconds that doesn't require healing until damage breaks past that portion, self or cotank.

By comparison, Rampart is +25% of current EHP.

Shelltron is +25% of current EHP, bypassed by Criticals, is Block, and therefore cannot stack with Parry.

Intervention is 11/11 to self and cotank, and adding 50% of additional cooldowns to your co-tank. By itself it is weak and requires additional cooldowns to bridge the gap.

Raw Intuition is +25% of current EHP, but locks out Nascent Flash, which is stronger. Nascent Flash, however, is sustain and is effectively +0% EHP to the Warrior, and +11% to the cotank. Nascent Flash won't prevent the 1shot.

Heart of Stone is +20% of current EHP to the target.

However, of all these abilities, TBN has the potential to fail and cost 500 / 300*Target potency if it doesn't break.

People like to focus on the extremes. The "Best case" is equivalent, and the "worst case" is significantly worse, but that big fat area in the middle, TBN generally stomps the rest.

The odds of failing the TBN win condition are pretty slim, but it can happen, and when it does, it is certainly the worst of the bunch.
