The on-use effect on Jotungeirr, Destiny’s Call doesn’t seem to be getting used for WW in the simulator. It works for other specs such as BrM though (and I saw a sim of it working for Feral in another thread). Makes it kind of hard to sim it against my other weapons. 
The buff is called Burden of Divinity, for reference.
