Updated Paladin Description

Blizzard updated the description of the paladin on their website. However, it's not quite accurate yet. I'll finish the job for them (changes in italics):

Upholders of the Holy Light and defenders of the Alliance, the Paladins can be found from the northern forests of the Tirisfal Glades, fighting back the advance of the Forsaken, to the southern reaches of the Blasted Lands, ceaselessly upholding their vigil against demonic forces from beyond the Dark Portal. Wielding their mighty hammers and the strength of the Light, these holy warriors command forces in battle, continuously throwing themselves into the fray healing the warriors wherever the fighting is the thickest.

The Paladin is a mix of a melee fighter and a secondary spell caster. The Paladin is ideal for groups due to the Paladin's healing, Blessings, and other abilities. Paladins can have one active aura per Paladin on each party member and use specific Blessings for specific players. Paladins are pretty hard to kill, thanks to their assortment of defensive abilities. The Paladin can also heal with Holy Light, unlike other combat classes. The Paladin is an Undead specific fighter as well, with several abilities designed to be used against the Undead (not the Forsaken though, they aren't Undead).

Paladins are the consummate knights clerics in shining armor, meant to be in the thick of things standing in the back. Their defensive abilities allow them to stand toe to toe with monsters and take a beating if the monster gets away from the front-line fighters. This is not the The sole purpose of a Paladin, of course, is to use their auras, seals, heals and resurrection spells give them the chance to act as a support healer.
