Have you looked at the PvP forum at all? Did you happen to see the September 1st post on the front page of
this site? Have you read any posts on this site PvP-wise since Cataclysm has been released?

Obviously, DKs are good at what they do.

Here's what I like to point out, though...

"Oh, this new team is so awesome at level 14 I'm owning BGs!!! lolol"
"I'm only level 42 and I'm such a beast! No one can kill me in BGs!!! lolol"
"Look at these stats from my last AV game. I'm only level 63 and I'm invincible!! lolol"
"Level 81 and I'm just plowing through the competition in BGs!!! I'm gonna be a badass at 85!!! lolol"

All of the above mean absolutely dick at level 85 when you are finally on a much more level playing field and
you encounter people who have lots of resilience, know how to play their class, and can PvP. Blizzard doesn't
balance the game around level 14, level 42, level 63, or level 74 for that matter.

Everyone is going to tell you that DKs are awesome because they are. It's like asking, "Hey guys, do you think
the new Lamborghini is going to be fast?"
How the DKs are used, is up to the player. My grandma could
probably roll through the level 74 bracket with 4 DKs. However, if it came down to being picked to be on an
RBG team then grandma would get picked last because she's actually a terrible player.

The real game of World of Warcraft doesn't begin until you're at the level cap. Until then, it's no secret
that everything is unbalanced.
