By no means take my word as gospel but since no one else has replied yet I'll give my two cents since Patch 2.1.

Internal Release: I still use this, for the chance to more easily 100% top me off before the big hit Inner Beast is supposed to be mitigating.

Second Wind: Use during Berserk to mitigate the loss of STR, it's still useful combined with a Storm's Path/Inner Beast.

Featherfoot: I'm getting tired of this ability, I don't think I've ever noticed an increase in my dodges, even for auto-attacks. Most notable raid boss attacks are unavoidable and must be mitigated anyway.


Haymaker: I think DRG and SMN or SCH can put up this debuff and I don't believe they stack. I don't think it's reliable enough to take a slot, nor even a GCD.

Awareness: Again, barely noticeable. I think it can give you a safety net vs. Auto-attack crits and therefore RNG but you can't 100% anticipate when something like this will happen.

Mantra: Limited range, but decent for periods of high sustained DMG where you won't be topped off for some time, e.g. Titan EM.
