Ok, so, many know the exploit where if you are a Gnome Twink you can stand where the chest will be and the chest will spawn on top of you if you log on. (Unless it has been fixed) Well now it works for both factions and all races! Just go to the Booty Bay Winter Gnome Turner-Into thingy and turn into a Gnome, from there follow this link for details: Easy Arena Master (gnomes only)
Oh yes, one last thing, the man who spawns the chest begins walking around at 3:00, 9:00, and 6:00, so make sure you get on around then.
