Currently I am playing as a Destro Lock with an Arc mage in 2s. I'm sitting around 1100 resilience in full pvp gear (except 1 ring, as there isn't much option in the second ring slot for spell casters). Currently I'm using [Medallion of the Horde] and {Battlemaster's Ruination].
However after looking through the armory's of some high rated warlocks I see many of them using DFO which I have for my PvE set. I Know the 150 haste and proc is great for burst dps however I feel like I would be losing too much survivability by giving up either of the pvp trinkets I have.
Currently I'm leaning towards giving up my Battlemaster trinket since I would still be over 3k SP have the healthstone.
Any input regarding PvE trinkets v PvP trinkets would be helpful, and more specifically any casters with arena experience that have used both would be great. thanks
