Quest NPC’s helping me in PvP battleground

I’ll be posting most of my Youtube video’s here eventually. Here’s one of the very first ones I uploaded. If you are not familiar with the game World of Warcraft than this will have little or no meaning to you. But for those who do.. it was a funny situation. I was in the middle of a lowlevel quest that instructed me to gather some npc’s and bring them to a certain place. When I gathered them and was on my way to deliver the quest, the queue for battleground suddenly popped. And to my surprise these npc’s I gathered also got ported to the battleground. That was something you don’t see every day. I’m actually thinking about leveling another horde char to the same, and try to perform this trick again. But, who am I kidding? I’v got my hands full enough with the new Legion content.
