TL;DR: What Major established threats haven't been seen or 'taken care of' in our timeline Azeroth?
Trying to see how many bad guys are left in our reality (ignoring any AU stuff)
To see where they can take the story next. I know Warcraft has no end, but from the original stories and RTS's it would be cool to know what established threats still exist that haven't been taken care of or even seen in World of Warcraft.
All I know is Demons/oldgods and well thats it really.
