PvP in Wrath

As I look forward to Wrath, I’m worried about having to PvP for PvE gear again.  I still use my PvP shield for tanking on my warrior despite having cleared Kara many, many times and having done a good chunk of ZA.  I’m bored with PvP and I really don’t plan on doing much of it come the expansion.  No incoming dramatic protest, I’ll just live with having sub-optimal gear if the optimal gear requires PvP to acquire.  If PvP becomes fun for me again, I’ll do it then.
