Haha, to play off of Remanz' post about the Rets at 85 I'll post my thoughts on the DK's so far:

I hit 85 on Thursday and I've done a total of 6 BG's since then. Me entire team died once and one of my DK's (carrying a flag) died another time. That's it.

I'm a complete wrecking ball. The damage that they do coupled with the defensive cooldowns that they have is insane. It's *even better* than how I thought it would turn out in my Manifesto.
