Actually, they use the power of the heretofore little dealt with in Lore sun god An'she, who may or may not be the same entity as the Holy Light. People are falling all over themselves trying to find a reason why the Light followed by the Tauren paladins and the Light followed by the Sin'dorei paladins (since the redemption of the Sunwell) and the Light followed by the human and dwarven paladins are three different things despite the pretty explicit and undeniable indenticalness of the Light they all follow.

Also: the goblins are not so much a Jewish stereotype in the new stuff so much as a hysterical, cackle-out-loud funny commentary on the horrors of modern corporate culture. No, really. I've been playing one since the friends and family alpha test.
