Seems in 4.0.6, our 4p for PvE has gotten changed.
The PvE hunter 4-piece set bonus has been redesigned. It now reduces the cast time of Steady Shot and Cobra Shot by .2 seconds.
While I do like this, I'm not sure as to whether this is a buff or nerf compared to the current 4p bonus. I guess this would allow for better reforging, as not as much haste will be needed to reach 1.66, but will that increase in stats make up for the loss?
