I'd love to see that titan mess (Not Ulduar) in Storm Peaks get used. There was so much cool stuff, that we did a few quests in them and never went back.
I really think The Great Candle deserves its own expansion.
Good article.
cool.
This is foreshadowing the grand return of ARCHAEOLOGY! Yes, we'll stick our shovels somewhere we were told not to and BAM! New patch content.
The elementals are coming.
Three-Falls Lookout in the northwest corner of Azure Span has some things alluding to stuff happening underground. During one of the quests there, you're attacked by a worm that burrows up from below and the questgiver comments on its habitat likely being disturbed. There's also a team of miners preparing to blow open a wall with explosives at the back of the camp itself, and they don't do anything with it by the end of the camp's quests. It's a pretty large pile of rocks, large enough to make a hole for players to comfortably fly through on their drakes. Unless this is related to a reputation-locked questline I've not done yet I'm guessing it may be a future entrance to the underground zone.
