I highly advise you Not to go wolf bones for PVP.
Wolf bones requires uptime on the target and good RNG to be any good at all.
On single target boss fights it has some value since the more time you are in combat the more likely it is you get some actual good procs (Although it has extremely big problems there aswell). Also Feral spirit is pathetic when it comes to damage as a damage cooldown so you basically do not have a big bursty moment either (Thats why DW is always selected cause enhance doesnt have a proper baseline cd ) . For raid scenarios Wolf bones is better than all the other choices since everything else lacks single target damage on longer fights.
The best stats for it tho is Haste/Mastery mostly.
If you really are bored of DW on PVP (many of us are) I recomend going Legacy of the Frost Witch build , it is not as good as DW but I’ve seen some people trying it out on PVP and it is more fun.
