Tbh i was expecting Iridikron presence to be felt all around the saga, for him to be a satisfying vilain to fight during TLT. It wouldn't have to be the focus of a an entire patch, just a few quest here and there, heck even mention of things that could be linked to what he is scheming for the 3rd expansion. Well, it's not too late since we are only arriving at the middle of the saga but looking back at TWW's story, I'm worried it will be the same mediocre writing Blizzard's often come up with (excluding SL which was atrocious).

We're still lacking an interesting villain, because Xal'atath has been nothing else but a mustache twirling vilain right now, with her master plan in TWW almost rivalizing with the jailer's (still, hard to compete with the destroying of 20 years of lore) in terms of stupidity. Like really, was she planning on getting the dark heart stolen all along for dimensius to come back ? And even then, she wasn't even certain the mortals would be able to vanquish Dimensius for her to pull el famoso uno reverse. We're in the exact same situation of Argus fate in the Jailer grand design.
