I look at these changes and kind of wonder what is going on. The fury tree is being nerfed, arms is getting no where, and prot is being for the most part left alone. This is putting us behind almost all classes in every aspect of the game. We won't be able to deal damage like we used to, PvP will still be hard, and we are finding ourselves still way behind DKs and pallys when it comes to tanking.
With the whole zerker stance change, I would think maybe they could afford to reduce the nerf to TG. In theory (correct me if I'm wrong) when you gain a buff (might, 1000 AP from MoT or AP from beserking) this scales with the current zerker stance, creating a very high amount of AP when these buffs are all together.
With the new zerker stance, I think maybe they should get rid of the TG nerf, and see how warrior DPS does then. If it is still too high, go to 5% instead of the 10%. If it is still higher then what they believe the hybrid tax should be, then maybe they can be justified to go back to 10% but I honestly doubt that will be the case.
