Deathwing has the latest model by Tauer since the last update. I couldn't find any updated dragon models of the other Aspects at the time of the update and I find it unneccessary to show the Aspects in their mortal (human) form when they have so little screenstime.
I don't mean human forms; I mean dragon forms.
Because unless I screwed up in downloading the latest versions; they're still weird and unfitting, like Malygos being an ice-crystal dragon.

Alexstrasza-- I didn't download her. I don't know if her model file is complicated or not to import, sorry.
