@ucaniguana We are working on something for this, hoping to debut it with 6.0. Should have more details soon.- Mumper (@mumper) July 1, 2014
Once upon a time, nightfall in Azeroth meant that things got truly dark--sometimes spookily so.

Plenty of players have been clamoring for a good long while for a return to the dark and eerie Azerothian nights, and it seems as though their wishes may soon be coming true. In the following tweet, Lead Game Designer Cory Stockton indicates that some kind of darker night-time atmosphere is on its way potentially as soon as patch 6.0.
