I play an unholy DK with 5266 resil (seems a bit overkill?) and I just never got competitive enough in PvP in Cataclysm like I did in the previous expansions. I am having a lot of trouble dueling Ret Pallys. Often I'm able to burst them down pretty quick, but they fear-spam the heck out of my ghoul/abomination repetitively, HoF, and then Divine Shield to heal all the way back up... how are we supposed to beat them? I have tried kiting, keeping desecrate up as much as possible, preserving my AMS for after Divine Shield wears off, using my ghoul stun and strangulate one after another, but they just continue to catch up with me and turn the tide of a match from me being at 80% and him at 20% to the total opposite. Now I'm not saying it's impossible and that I've done it perfectly, but what are your suggestions? I have found the best strategy is to take the offensive initiative from the get-go but it doesn't help me quite enough. Are DPS DKs just doomed for dueling in Cataclysm?
*Edit - I am spamming necrotic strike as often as I can.
