Hey, tweaked yours a little to work for me. changed Bear form to Buff: True (not it doesn't go in and out nonstop while trying to fight.)
Also changed Frenzied Regeneration to Health Percent: Smaller than 95% (priority 50) this way it casts it nonstop so every bit of rage is used, cause when it was on rage condition, never used this at all. These small 2 things changed the profile to completely perfect for me. now it kills without stopping.
