I've been soloing scholomance heroic for quite a while (got my 150th Rattlegore kill today) and Doctor theolen krastinov still didn't spawn. I know it's probably just bad rng but i'm starting to think he can only spawn when you que via dungeon finder. GM said that they are not allowed to tell me anything about it. Is there anyone here who can confirm that he saw the spawn by simply running in the instance instead of dungeon finder que? Thanks
