If nothing else, the timewalking dungeons in World of Warcraft have proven a great opportunity to look back at dungeons that you may have forgotten about altogether. When was the last time you really thought about the Halls of Lightning? It exists, it can be timewalked through during the Wrath of the Lich King timewalking event, and it features plenty of shocking challenges for even veteran players. Or not very shocking if you read up on the mini-guide from the official side, which details all of the dungeons mechanics. (They involve electricity.)
The official site has also unveiled both the goodies from the current San Diego Comic-Con and some of the revelations from the show floor, including the first installment of the Warcraft Chronicle looking back over the franchise lore and history. Check out the start just below if you aren’t on the show floor yourself, which seems rather likely if you’re reading this.
