So in the updated patch notes ravage will have no facing requirement either, I honestly can't understand this change outside of it being an intended nerf to PvP.
Ravage gets used at max once per fight in PvE, and if you do take the talent (which nobody does) it already removes the facing requirement. The effect of ravage having an inherent directional requirement brought it off the dodge/parry table completely, including when under the effects of incarnation. This attribute allowed for the bypassing of things like Evasion from rogues and Die by the Sword from warriors.
Now that druids have 0 abilities which require being behind target, these effects will completely shut damage down, because everyone knows that with even an ounce of latency in pvp, you can't really tell if you are actually behind a target without spamming these abilities. Seems a bit odd to me that the justification is that ravage is hard to use now, even though it is only used on the opener or under certain effects which remove the facing requirement anyways.
A small gripe, but overall I feel it is just removing an aspect of facing requirement that actually felt good to me, including the facing requirement on shred as well.
