TBN is great in concept but has some flaws. The punishment is too much for a missclick, no other tank gets punished so hard as DRK, maybe a WAR using infuriate during Inner release is a second close but that is a job mechanic mistake and not a timing mistake.

As you get stronger, it is harder to pop TBN, your iLV increases and the encounters become more unpredictable, some (me included) like to open with TBN to get maximum profit from blood weapon from the very first GCD on the fight, now the bosses autos are enough to pop TBN but in 5.1 maybe will not be anymore...
