Here's a somewhat annoying little problem with the Beta. As of the latest build, you can't just walk into Dalaran, or rather, you can't just use the teleportation crystal go up. Instead, you have to complete a quest to align yourself to Dalaran. But this quest is only available at level 74.
In the Outlands, it's not uncommon for a fresh 58 to head through the Dark Portal and right to Shattrath City. Binding in one of the Inns there essentially puts all of the Outlands before you, with flights connecting you easily to where you wish to go.
It seems strange that Blizzard has put up this strange quest attunement roadblock to those who wish to alight from the boat to Northrend and head straight to the capital. Perhaps it's a similar decision that caused them to restrict flying mounts to level 77 and above -- they don't want people skimping on exploration and seeing content, so they make you hang around the newbie zones for a while before you can just stick with Dalaran.
Luckily, not all is completely lost. Much like with Shattrath before level 58, You can still get teleported or summoned up by a Mage or Warlock before level 74. Still, it's a strange little extra hoop Blizzard's having us leap through to get the to top.
