A hotfix has been made that no longer allows Warlocks to summon players while in a Battleground.

The reason for the change is that it was being used to exploit Battleground mechanics, most notably flag captures. We realize that its use in Alterac Valley was useful as the battleground is much larger in size, and it was with much disappointment that we had to make the change to keep players from exploiting its use in other Battlegrounds. At current the rules extend through all Battlegrounds which we find also helps maintain a consistency of rules and mechanics, but we will be watching the impact of the change.
