There is a great cieling to learning the timing for TBN. If you only cast TBN on reaction to a cast bar coming up you are absolutely not mitigating as much as you could.
In Malikah's Well the second boss, Amphibious Talos, will do a tank buster shortly after he finishes his rotating cone attack then not long after he will do another tank buster.
If you use TBN right when you see the cast bar for the first tank buster or pre-cast it you will have just enough time to use TBN for the second tank buster as well.

Also there are plenty of opportunities to use TBN for bosses other than just tank busters. You just have to look for those opportunities.

Unfortunately, people are not looking because they have a mentality of "TBN and similar cooldowns = tank busters only"
