Not sure if this has been posted but additional new changes for warriors on 5.3 PTR Patch Notes.
Enraged Regeneration no longer costs rage to use, instantly heals the Warrior for 5% of their total health, and healing an additional 5% over 5 seconds. Using the ability while Enraged doubles the healing effects to 10% of the Warrior's total health and an additional 10% over 5 seconds.
Second Wind no longer generates rage when the Warrior is struck by a Stun or Immobilize effect.
Arms and Fury Warriors receive a passive ability that enables them to generate rage when struck by a Stun or Immobilize effect at level 56.
Shield Wall's cooldown has been reduced to 3 minutes, down from 5 minutes.
Spell Reflection is no longer consumed by spells from player pets and guardians.
