I don’t like Odyn personally, but his initial objections to the Dragon Aspects don’t seem entirely unfounded now. Malygos went insane and tried to hoard all magic, Ysera was corrupted by the Nightmare, Nozdormu ends up turning into Murozond, and Neltharion is responsible for a planet-shattering Cataclysm.
I think the Aspects were a good idea on the part of the Pantheon, but after all this, it’s hard to not see where Odyn was coming from.
