I'm not quite done with this questline, but all was well up until Dashel Stonefist's part (quest/mob) - not a big deal, but defeating him the first time did not complete the quest. I abandoned it and tried again and was able to continue.
However, the questline soon took me to Menethil Harbor to talk to the barkeep, where was I was to 'stop' Tapoke "Slim" Jahn from escaping (quest/mob). This scripted event did not occur, and Tapoke never spawned. Not a problem, per se, as I was immediately able to simply talk to the barkeep to continue the questline.
The questline then moved me onto Theramore, where I was to search for a guard in a tower. Now my memory from vanilla, and Wowhead confirms, is that in the tower Archmage Tervosh should be there to tell you that Jaina was looking for you (quest/npc). No such scripted event occurred, the mage npc needed to finish the quest was simply not there. Without looking it up, it would be impossible for the average person to possibly know how to continue this quest line. But, once again, I was still 'able' to complete the questline by manually walking myself back into town to find and talk to the mage at his other location. Even in vanilla there were some problems with this npc in particular, as he teleports himself around and still has the exact same npc id in both locations. I also hear he's supposed to cast this spell on you as you move onto the next part of the questline (and that also did not occur).
So, after beating up Hendel (quest/mob), according to this post, Jaina and Archmage Tervosh should teleport to my side. Once again, no teleporting of npcs happened, but I can turn in the quest after running all the way back to town (this is starting to get tedious).
For now I'm just saddened by the missing flavor and this is as far as I've gotten so far in the questline, so -- I'll report back if there's anything else down the line.
