from my experience on mythic, fury still ahead just slightly over arms on single target fights (kargath butcher) in korgath arms is owning cuz u can use execute when his shield is low, but guys dont leave fury to soon, we know arms is broken as f atm and blizz will not let this happen.
arms was re nerfed for people not up on things. unless this post was made after that point. (didnt check)
