So I’ve been leveling a DK and so far I must say, OP all the way. I’m 72 at the moment but that does stop me from destroying higher level classes. 75 Undead Rogue? No prob. 74 Blood Elf Warlock? Peace of cake. 76 Blood Elf Hunter? What huntard?
The only class that’s given me problems are other DKs. And even then, most of them die to my wrath.
