Personally, I've not yet spoiled the artifact quests for myself, so I'm really looking forward to all the lore that comes with those, especially after the Warcraft Chronicles! Also Dalaran, can't forget that, since it's been a while. It used to crash some of my old guldies' games or when there were less people bring them down to 1-10 fps. Let's hope that doesn't happen this time!
