Warrior Protection Spec Enrage Passive

[mibeal]

• Undead Warrior Protection Spec
• [Problem Description] Enrage passive (Spell ID# 13046) is not activating when getting a critical with Devastate or Shield Slam as indicated by it's tooltip.
• [How it should work] When getting a critical hit with Shield Slam or Devastate in protection spec you should gain the enrage buff for 6 seconds.

Note: I was able to make the buff work after using .unlearn 13046 and then using .learn 13046 on my character. The buff now works properly, for some reason upon auto learning it while leveling it would not activate.
