Deathknight's do it using disease, blood and the power of the unholy. Warlocks do it with dark demons by their side. Mages do it with summoned arcane powers. Druids do it using the forces of nature. Rogues do it through stealth, poison's, shadows and....from behind. Paladins do it by calling to the light for aid. Shamans do it with the help of the elements. Priests do it through the holy light.
But warriors....
Warriors just fucking do it.
Perhaps it's just a quest where you pick it up and smack people about a bit. Maybe a mechanic in an upcoming raid like Kael'thas where you pick up legendaries for the fight, say the npc's get smacked about by grommash and you have to pick up their weapons and go to town on him (Khadgar's Atiesh, Doomhammer, Maruud's Hammer of the Naaru, etc.)
