Hyjal
Although Hyjal is for the most part spawned it is not yet ready for use. If you attempt any bosses in Hyjal expect a timely demise.

As statded in the forumer.com/viewtopic.php?t=539>Scheduled Maintenance post: Attunement for Tempest Keep: The Eye has been removed Hyjal is now opened to those who complete the attunement. Since the attunement for Hyjal is essentially the same as the custom quest that was made for BT, at this time BT and Hyjal both have the same requirement to enter. Therefore if you have completed the BT Key quest you should be able to enter Hyjal as well. As for the quests not giving rep, I will certainly look into that.
