Just wait till my undead shadow priest hits level 60, Shadow Priests can pretty much own any class 1 on 1
Oh well, I pwn warriors,hunters,mages,druids and shamans pretty easy. Every now and then I meet someone of the class listed as easily beatable that actually knows how to use their class and puts up a fight. But the warlock and shadow priest... they don't even have to know how to use their class to kill me.
So what do you do? Stay stealthed till their off guard and take them out. Rogues aren't meant to be the best fighters because they often times pick their own battles.
