So I took a trip back into Warsong Gulch recently, and discovered that, true to what people in my comments said, the Death Knights aren't an insurmountable hurdle.
I'm going to be working towards trying to get some of the Resilience gems and gear from Wintergrasp, as I still want my Conqueror title if I can get it. The games I've had so far have gone ok, though.
I might not be raiding, but I like to think that where Warsong Gulch is concerned, I've still got it. ;)
