hows pvp as a max level alliance warlock?

when anniversary came out i made a ally lock, by the time i hit 40 i ended up re-rolling because because it seemed like just a whole race of any class partially countered me in pvp. sure i could bait out the racial but this could double / triple the length of a fight, even if i managed to out skill a unfair advantage most of the time help arrives before we can finish the fight. now that bgs are out and trinkets are a thing, does undead racial share a cd with the trinket? or is it double jeopardy?
