Need Advice for Speccing

Hi! i have a feral druid with 4.3k gs.

I really love PvP with feral but dreaded the PvE side of things. i dont really like PvE in the first place. but, i need some advice.
Since most of the guide i've read on Feral PvP mentioned one or more PvE items as the BiS (Such as Oathbinder), i wonder if i should continue PvE-ing as a feral?
I would really like to spec Balance as my PvE but at the same time i would like to be able to have the opportunity to complete BiS set for my feral PvP.
Any advice?

Well it's simple to say.
Best is to continue to play Feral in PvE. Why?
Well if you play Balance you will need to spent DKP to gear up that Balance Druid in order to get into raid good enough that can do LoD.
All of that DKP spent on Balance gear could be spent on Feral gear instead.
You will have to do the same for your Feral, but at least you can use a lot of PvE Feral gear in PvP, not just the weapon and trinket.
