They've set up this huge plot line that doesn't seem to be getting any development until 7.3 at the earliest.
Odyn is free now, he stated he was heading to Ulduar.
Is he going to work with the other Titan Watchers to awaken Azeroth? Give up their Titan spirits to fire up that big engine in Storm Peaks?
If Azeroth is indeed a Titan, how do we bring her with us to fight Sargeras? Build a portal on Argus? Tow her behind the Exodar?
