[Declined] Darker non-Legion nights [In-game]

[Bregalad]

Title: Darker non-Legion nights

Type: In-game

Description: 

In Legion, the Potion of Inky Darkness was added to the vendor at the Darkmoon Faire.  It makes the nights much darker and has a two-hour duration, though the effect is lost if the character dies.   

Would there be some way to make this available for the expansions prior to Legion?  It's a great effect and really adds to immersion, plus it is player-controlled so those who like dark nights (or days) can have them and those who don't, don't have to.
