Gift of the Earthmother now increases your total spell haste by 2/4/6/8/10%

From the PTR patch notes. Nourish already clips the GCD with Nature’s Grace active. This will benefit mainly healing touch and regrowth, both of which are extremely niched to begin with. The removal of a tick of rejuvenation is already a substantial nerf. This will nerf our general raid healing further beyond substantial. The addition of the glyph is only a situational buff (as already discussed in this article).
