And while we're at it, Flintlocke isn't the only show in town, although it is a show that I really like. If you've never seen the Heroes of WoW series, it's definitely a good read (it's originally a German comic, actually). Looking for Group has been seeing a gain in popularity lately, and it definitely looks great, too.
And no discussion of WoW comics is complete without a mention to Dark Legacy comics, also a terrific comic series based in the world of Azeroth. Those are all the ones I can think of off the top of my head-- know any more to recommend?
