The Battle for Shattrath

I’m working on unlocking flying in Draenor and as such I’m working on the “Don’t let the Tala-door hit you on the way out” achievement. The next quest it says I need to complete is “The Battle for Shattrath”. Everywhere I’ve looked says that Archmage Khadgar is the NPC that starts that quest and he should be located at 54, 36 but he is nowhere to be found anywhere around there. I’m sure I’m missing a quest that puts him there but for the life of me I can’t figure out what quest I need to complete first. Can someone please give me some help? Thanks in advance.

He’s not actually there, IIRC. It says meet him there, but he’s at the quest-giver instead. It was irksome finding him the first time.

I guess it could be zoning issue, too, but my bet is on the map being wrong.
