This is what I've been using:

Ravage is definitely worth using now IMO, since they made it un-interruptable and buffed its dmg 15%. That plus the 2 points in ravager makes it hit like a truck, and because it doesnt cost any rage you are always ready for the next deadly sabers or annihilate. Also because this spec uses ravage the 2 points in empowerment aren't needed simply because you'll always have enough rage without it.
The extra point can go wherever you like, I put it in defensive roll.
Edit: @ Omite, you obviously don't use ravage over the big 3 (deadly sabers>rupture>annihilate) but it replaces vicious slash nicely as a filler.
@Daystarr, Check your spec you got a free point laying around, also read the title this is about PVP not PVE therefore subjugation is a *MUST*.
