Raging Whirlwind in the Prestige AA tree has not scaled well over the past few years and is significantly worse than the ability (tempest) it replaces (even factoring in it is an aoe). Because this ability is an AA and can't reach celestial level, the debuff associated with Tempest of the Elements is significantly smaller as well.
I suggest increasing the overall damage of the ability and allow it to receive the ancient/celestial version of the Tempest of the Elements debuff.
