Bestial Wrath and [The Beast Within] changed to function like PvP Trinkets, removing any movement impairing effects and giving immunity to these effects for 10 seconds. The tooltip doesn't say this, but it also now breaks all forms of CC that a PvP trinket would break (including Cyclone, Sap, etc.).
Patch 2.1.0(2007-05-22): The immunity granted by Bestial Wrath now lasts the full duration of the ability. It also now grants immunity to [Cyclone].
