Blizzard has released 11 instructional videos designed to give a new level 90 a quick and dirty introduction to their class. The title is perhaps a bit misleading, because these are not complete class overviews. Instead, each video focuses on a particular specialization of that class--and specifically, a DPS specialization. The specs featured are: Frost death night, Balance druid, Survival hunter, Arcane mage, Windwalker monk, Retribution paladin, Shadow priest, Combat rogue, Elemental shaman, Destruction warlock, and Arms warrior.
If you've got a brand-new 90 that you're still figuring out, or if you're looking to busy yourself learning a new aspect of your class before Warlords of Draenor, these might be of interest to you. It is nice to see a Blizzard-sponsored guide for specs such as the Balance druid, which I personally find annoyingly complicated to play, but I'm a bit puzzled by the extremely specific nature of the videos. Are there going to be further guides for tanking and healing specs? Or for the DPS specs not covered here, such as Affliction warlocks, Fury warriors, Feral druids, Subtlety rogues, and more? I think videos like this that come straight from the horse's mouth of Blizzard are a great idea, but it's strange to see a set of them that feels so incomplete. Still, if you're toying with the idea of learning one of the specs covered, the videos are a good place to start.
