Well, it seems to be up, and I was initially shocked at how limited the selection in Dragon was... before realizing this seems to be the month for the split between DM and Player content. I think. Hard to tell how much of the Dungeon content is adventures and how much more general articles. With that in mind, the articles do make a bit more sense.
Dragon has an article on the Great Weapon Fighter, essentials for the Cleric and Warden, a new Adventurers of the Realms article, and finally a series of three articles for the Assassin at the different tier. Which is... odd, but I'm hoping that means they are presenting not just the class, but full support for it - significant feats at each tier, along with a selection of Paragon Paths and some Epic Destinies. That would be a lot more than I was expecting, and be very satisfying to see!
The focus is still a little limiting in my eyes - the fact that every single article is centered on a specific class - and I'm hoping that is just how the pieces fell into place and not the start of a trend. I'm definitely a fan of articles that are a blend of flavor and mechanics - stuff that encompasses entire themes (Gladiators/Art of the Kill) or groups (White Lotus Academy, Sons of Mercy, Champions of Bahamut). I've no objection to the Class Essentials articles - I think they are very useful material - but I want a mix of content rather than just one thing.
