The Azeroth Advisor is, according to their FAQ, “an electronic newsletter that is personalized to your World of Warcraft characters. It is automatically delivered to you by email, customized to your character’s current level and status. Our idea is simple: give you the information you need when it’s relevant to you. The Azeroth Advisor is not a cheat guide or a set of walk-throughs; it is insightful guidance that helps you make informed decisions throughout the game.”
This service used to come at a cost, but now that 38 Studios has purchased it they have made it available free of charge. Very generous of them, considering that they are making an MMO to compete with World of Warcraft. So why would they do this? Seems obvious to me. They plan to offer this same service to players of their game when it goes live. Smart move on their part. This sort of value-added bonus for their future subscribers shows the forward thinking that is going on over at 38 Studios. I applaud them for this move.
