The first and most obvious layer is Wowcrendor's deep affection toward Dalaran and his surprisingly powerful language regarding it. He describes the city in beautiful language, using potent, poetic phrases.
The second layer of messages comes when the other characters react to Wowcrendor's speech. The "chorus," as it were, remains completely oblivious to the elegant design of Dalaran. They remain focused on portals and teleports, missing the engaging, architectural beauty of the city. For better or for worse, Dalaran was definitely a pearls-before-swine moment.
