The nerfs do make some sense in regards to talents. Wrecking Ball is probably a clear winner in anything but a pure single target situation, and the nerf to Raging Blow definitely buffed Frenzy.
I was really enjoying an Avatar/Carnage/Inner Rage build on single target, and that didn't feel like it needed much nerfing but alas. We shall see I suppose. With the nerfs once you get Juggernaut I think Frenzy will just dominate to be honest.
