Okay this is my first contribution to the site and I really hope it help, while you are doing this quest all you need to do is get your pet out, put it close to Incandescent Flare Sparks while their are being killed, it doesnt matter if you are the one killing this mobs or its a horde/alliance, so you can save time by just releasing the pet and flying around to close players killing the npcs and you will be done with the quest pretty soon without even having to kill one single mob.
