I know, for instance, that my three favorite lost concepts will finally get treatment, namely the creation myth surround the dwarves in Uldaman, Dalaran the bubble city, and the mysterious Grim Batol. I also know that one of my favorite characters from the War of the Ancients trilogy will finally get into the game, the red haired mage Rhonin. But what happens to his twin children, and his wife, the sister of Sylvanas? What will happen to the area where Dalaran is currently? Will they update the quest in Uldaman to reflect the additional info about the creation myth?
You see what I mean? The more questions are answered, the more arise. It's a vicious, tantalizing cycle, and one I am definitely enjoying being caught up in.
