I picked up the link to this blog, Blessing of Kings, from the VirginWorlds news feed. The news item involved two entries titled “So You Want to be a Raider” Part I and Part II. Both of those post are worth your time.
But I spent some time going through the site. It is a blog about a level 60 Paladin exploring World of Warcraft end game content. It contains a huge amount of information on playing a paladin and raiding in general as well as a narrative of the author’s experiences over nearly a year. It is a good read that will give you insight both into end game content as well as a Paladin’s role in that content.
