Issue with TBN

[Interovegas]

"there are a lot of enemies hitting me, time to TBN."
"this is a tank buster about to hit me, time to TBN."

so thought intensive.

The ability to clear dungeons is not the premier quality most people look for in a class. In high end content the 15 second cooldown of TBN motivates me to learn when to precast TBN in a fight to have it up and ready to soak more busters more often. 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.
