Now that Wrath of the Lich King and its first hero class is in the works, I've been thinking on the shifts the paladin has made in Warcraft of late. I'm not so much talking about how the class plays, but more what the class is about, its roots and changing story. Originally paladins are the holy warriors of Azeroth, wielding the power of the light of some divine entity, able to heal and to harm with its touch.
When The Burning Crusade was released, the paladin class was added to the Horde faction, and we learned that this type of Paladin was a very different breed. The Blood Elf pally was a warrior who drew on the light as well, but funneled from a holy being. This parasitic nature of the paladin was definitely a dark twist on what was considered a decidedly good-goody class. Now the paladin was sucking the power they used from a captive Naaru.
