How does Turalyon become High Exarch?
How does Alleria visit AU Draenor without passing through the altered Azeroth Dark Portal (since she obviously wasn't present during Garrosh's trial in War Crimes when Garrosh and Kairoz first came to AU Draenor)?
Why don't *any* demons from the Nether mention or otherwise allude to him ever, especially if they've fought against them for what would be 1,000 years to both parties?
The demons don't speak of them, the Draenei don't know them, etc. etc.
