Update:

I've changed some things within the rework in the OP.

Highlights include:

* Defiance is no longer gained from taking damage and is now only generated through actions.

* Defiance gauge no longer grants max health and healing received and instead gives Parry.

* Butcher's Block combo no longer has increased Enmity gain, instead enmity is focused solely into Unchained.

* Butcher's Block no longer grants MP and instead gives a 10% DR buff.

* Gauge Spenders are no longer tied to combo's and are instead readily usable (Provided you have the 50 Gauge to spend)

* Overpower and Storm's Eye combo's no longer generate gauge.

* Infuriate reworked into Furious Guard, allowing for an Active Mitigation effect that can be timed for DPS increases.

* New Trait Fractured Earth at level 66

* New Skill Furore at level 72

* New Trait Deep Wounds at level 74

* New Skill Inner Calm at level 76

* New Trait Magic Counter at level 78

* New Skill Tectonic Fissure at level 80
