Is TBN a bad skill?

[Lucy_Pyre]

Imagine thinking that the objectively best mitigation skill in the game is a 'bad' skill.

This skill doesn't needs changes.
It is powerfull shield which will hurt your damage if you use it mindlessly.
There is reward for using it right and punishment for using it wrong.

All these people saying TBN is DPS neutral when it breaks and very few who are mentioning that it's actually a gain when used properly. Yes on the surface it appears that you are only being refunded the MP cost with a free Edge of Shadow, but you can hold that Dark Arts proc to get an extra Edge inside of a burst window. If you can manage to do this every minute it's a pretty nice gain over a 10min+ fight. I like the skill as it is, and if they DO end up making any adjustments to it just adding 1-2 seconds to the shield duration would be enough.
