Dunno why you'd make these assumptions.
Probably not paladins.
Shamans yes, the entire start of the aspects and flights was that they had the special innate ability to use elements, one of the flights is wholly devoted to an element, two others constantly use them.
Probably not monks because awkward animations.
Priest, yes plenty of twilight using drakes.
DK, yes. (no reason not to now that the DK intro, like Exile's Reach isn't time setting specific.
Warrior, hunter, rogue, yes.
Mage yes, warlock yes.
Druid potentially because the entire green flight is druidic.
So: Priest, Mage, Warlock, Rogue, Druid, Shaman, Hunter, Warrior, DK.
Dunno if nobody has noticed cus it's so late/early, but all the images hosted on Imgur have been taken down by Blizzard, if you needed any confirmation the Dragon race, evoker class and talents were real.
For me its also 2457.
I suppose if the dragon race got druid as a class then we could potentially get some badass looking dragon-forms to tank, heal and dps in, so that could be dope even though I'd much rather have a class based around dragon gameplay
So a race with a single class? Considering we've seen a customization screen with a human on one side, and all pictures of the dragon form show them without gear or weapons, I'm leaning towards it being an "advanced" metamorphosis, which allows players to customize their dragon form, but only a bit. Those dragon forms would be shared between all races that could be this class, and maybe the humanoid character also has a few customization options (there was an image of a human with scales, fin-like ears and horns), but this would probably limit the number of races that have access to said class.
Also this one

1229 for me. I love 40-comments-per-page, never going back.
