I worked out why the most recent pre-Legion quest was so short.


Think about it - a mage's teleport spell has a 10 second cast time. If it takes 10 seconds to teleport a single person, it's going to take longer to teleport a city. If we assume that Dalaran has similar mass to 50,000 people, it would take 500,000 seconds to cast the teleport spell, or 5.9 days - approximately the amount of time before Legion comes out.The next quest you'll get is to come and feed Khadgar Doritos (exactly 47 of them) while he channels the spell.
