What is the reason for

[Miylee-twilights-hammer]

Here:

Queue for Battlegrounds from Anywhere

With tonight’s maintenance, we’ll apply a hotfix that will add the ability to queue for Battlegrounds from anywhere in the world. This will allow players to continue exploring the world while also participating in Battlegrounds. You’ll find it in the Battlegrounds tab on the PvP menu. Battlemasters are not going anywhere, so you can still talk to them if you prefer to.

Edit: someone beat me to it.
