Wow I met a really bad DK, he was 59 I was 47 and I kicked his stuff.
DK got nerfed so much, it's not even funny.
Even though, with the right equip and the know-how..
I have no problems beating the stuff out of hunters, other DKs and palas. I only have problems against mages, priests, warlocks and warriors (damn warriors and their stun :c ).
