Internal Release, Fracture, Bloodbath and Second Wind.
Fracture + Phlebotomize are just too good and fit in our rotation so well that is almost like Fracture was done for Dragoons, not Warriors.
Bloodbath, with our DPS, allow us to keep the engage even against heavy DoT situtations and relief some of the pressure over our healers. (With internal release we become half inmortal)
Second Wind, just too good to miss, can help you survive several burst attacks over you, is just an emergency button.
I dont think i should explain IR.
