My druid:
Msbobmarley - Arathor EU
I went for survivability with this toon, not BiS you could get better legs and trinket from raiding. I go with 816 res, with flask it gives me 866 which is 49.99% mitigation. I find I have more than enough spellpower, heals are still pretty strong and my regen is fine as I do not arena on her.
Almost hit capped and 49 spell pen, not perfect but fine for normal BG's which is pretty much all I do on her for PvP. You would probably want to hit the caps if you do arena. Yes it is still possible to die. I have had rogues kill me with 866 res and glyphed Barkskin up if my trinket was down.
Carry a staff with spirit gems and 45 spirit enchant on, you can macro it out when you need more regen or with innervate for faster regen. I use the one from Heroic Magister's Terrace with the 3 gem slots. As I do not raid on her, it is a realistic set. If you raid, of course you can get better.
Hope it helps a little.
